| 1 | Microstructure and domain engineering of lithium niobate crystal films for integrated photonic applications显示文摘Recently,integrated photonics has attracted considerable interest owing to its wide application in optical communication and quantum technologies.Among the numerous photonic materials,lithium niobate film on insulator(LNOI)has become a promising photonic platform owing to its electro-optic and nonlinear optical properties along with ultralow-loss and high-confinement nanophotonic lithium niobate waveguides fabricated by the complementary metal-oxide-semiconductor(CMOS)-compatible microstructure engineering of LNOI.Furthermore,ferroelectric domain engineering in combination with nanophotonic waveguides on LNOI is gradually accelerating the development of integrated nonlinear photonics,which will play an important role in quantum technologies because of its ability to be integrated with the generation,processing,and auxiliary detection of the quantum states of light.Herein,we review the recent progress in CMOS-compatible microstructure engineering and domain engineering of LNOI for integrated lithium niobate photonics involving photonic modulation and nonlinear photonics.We believe that the great progress in integrated photonics on LNOI will lead to a new generation of techniques.Thus,there remains an urgent need for efficient methods for the preparation of LNOI that are suitable for large-scale and low-cost manufacturing of integrated photonic devices and systems. | Dehui Sun Yunwu Zhang Dongzhou Wang Wei Song Xiaoyan Liu Jinbo Pang Deqiang Geng Yuanhua Sang Hong Liu | 2020 | Light(Science & Applications)2020，9，1： | 7 |
| 2 | WSe2 2D p-type semiconductor-based electronic devices for information technology:Design,preparation,and applications显示文摘The pioneering exfoliation of monolayer tungsten diselenide has greatly inspired researchers toward semiconducting applications.WSe2 belongs to a family of transition-metal dichalcogenides.Similar to graphene,WSe2 and analogous dichalcogenides have layered structures with weak van der Waals interactions between two adjacent layers.First,the readers are presented with the fundamentals of WSe2,such as types,morphologies,and properties.Here,we report the characterization principles and practices such as microscopy,spectroscopy,and diffraction.Second,the methods for obtaining high-quality WSe2,such as exfoliation,hydrothermal and chemical vapor deposition,are briefly listed.With advantages of light weight,flexibility,and high quantum efficiency,2D materials may have a niche in optoelectronics as building blocks in p-n junctions.Therefore,we introduce a state-of-the-art demonstration of heterostructure devices employing the p-type WSe2 semiconductor.The device architectures include field-effect transistors,photodetectors,gas sensors,and photovoltaic solar cells.Due to its unique electronic,optical,and energy band properties,WSe2 has been increasingly investigated due to the conductivity of the p-type charge carrier upon palladium contact.Eventually,the dynamic research on WSe2 and van der Waals heterostructures is summarized to arouse the passion of the 2D research community. | Qilin Cheng Jinbo Pang Dehui Sun Jingang Wang Shu Zhang Fan Liu Yuke Chen Ruiqi Yang Na Liang Xiheng Lu Yanchen Ji Jian Wang Congcong Zhang Yuanhua Sang Hong Liu Weijia Zhou | 2020 | InfoMat2020，2，4： | 5 |
| 3 | Calcium ion pinned vanadium oxide cathode for high-capacity and long-life aqueous rechargeable zinc-ion batteries显示文摘Rechargeable aqueous zinc ion batteries (ZIBs),with the easy operation,cost effectiveness,and high safety,are emerging candidates for high-energy wearable/portable energy storage systems.Unfortunately,the unsatisfactory energy density and undesired long-term cycling performance of the cathode hinder the development of ZIBs.Here,we report the chemical preintercalation of a small amount of calcium ions into V2O5 as the cathode material.The cathode of Ca0.04V2O5·1.74H2O (CVO)was demonstrated to have a high specific capacity of 400 mA h g^-1at the current density of 0.05 A g^-1and 187 mA h g^-1at 10 A g^-1,along with impressive capacity retention (100%capacity retention at 10 A g^-1 for 3,000 cycles).Meanwhile,the CVO//Zn battery exhibits a high energy density of 308 Wh kg^-1and a power density of 467 W kg^-1at 0.5 A g^-1.The superior performance originates from the pinning effect of the calcium ions and the lubricating effect of the structural water.The energy storage mechanism of the CVO cathode was also investigated in detail.The new phase (Zn3(OH)2V2O7·2H2O) generated upon cycling participates in the electrochemical reaction and thus contributes to the excellent electrochemical performance.The small amount of Ca^2+ pre-inserted into the interlayer of V2O5 sheds light on constructing cathodes with high energy density for ZIBs. | Min Du Feng Zhang Xiaofei Zhang Wentao Dong Yuanhua Sang Jianjun Wang Hong Liu Shuhua Wang | 2020 | Science China Chemistry2020，63，12： | 2 |

| 6 | Intracellular pH-responsive iron-catechin nanoparticles with osteogenic/anti-adipogenic and immunomodulatory effects for efficient bone repair显示文摘Osteoimmunomodulation was identified as a new and important strategy to enhance osteogenic differentiation together with other osteogenic approaches.However,approaches regulating osteogenic differentiation and macrophage polarization to remodel an osteoinductive microenvironment are separate and complicated.Therefore,the design and synthesis of one biomaterial that couples the osteogenic performance and immunomodulatory ability is a major challenge for efficient bone repair.In this study,self-assembled iron-catechin nanoparticles(Fe-cat NPs)were designed based on the coordinated reaction between iron ions and catechin and synthesized via a facile one-pot strategy.Interestingly,Fe-cat NPs show intracellular pH-responsive disassembly and release catechin molecules under the low pH of lysosomes after endocytosis.This strategy delivers catechin intracellularly and then enhances the osteogenic differentiation while inhibits the adipogenic differentiation of human adipose-derived stem cells(hADSCs).More importantly,Fe-cat NPs remodel the osteogenic immune microenvironment by resisting inflammation and promoting M2 polarization of macrophages.As a promising metal-organic nanodrug,the intracellular pH-responsive Fe-cat NPs significantly enhance the therapeutic effect of bone regneration by orchestrating osteogenic differentiation and immunomodulation,which may have great potential in bone tissue engineering. | Ying Kong Feng Liu Baojin Ma Wenhan Wang Liang Li Xiaoying Xu Zhaoyang Sun Hongru Yang Yuanhua Sang Dong Li Gang Li Chao Liu Shuhua Wang Hong Liu | 2022 | Nano Research2022，15，2： | 1 |

| 8 | Nonlinear interaction between broadband single-photon-level coherent states显示文摘We experimentally demonstrate the nonlinear interaction between two chirped broadband single-photon-level coherent states. Each chirped coherent state is generated in independent fiber Bragg gratings. They are simultaneously coupled into a high-efficiency nonlinear waveguide, where they are converted into a narrowband singlephoton state with a new frequency by the process of sum-frequency generation(SFG). A higher SFG efficiency of1.06 × 10-7is realized, and this efficiency may achieve heralding entanglement at a distance. This also made it possible to realize long-distance quantum communication, such as device-independent quantum key distribution,by directly using broadband single photons without filtering. | YUANHUA LI TONG XIANG YIYOU NIE MINGHUANG SANG XIANFENG CHEN | 2017 | Photonics Research2017，5，4： | 1 |

| 10 | Oxygen vacancies and N-doping in organic–inorganic pre-intercalated vanadium oxide for high-performance aqueous zinc-ion batteries显示文摘Pre-intercalation of metal ions into vanadium oxide is an effective strategy for optimizing the performance of rechargeable zinc-ion battery(ZIB)cathodes.However,the battery long-lifespan achievement and high-capacity retention remain a challenge.Increasing the electronic conductivity while simultaneously prompting the cathode diffusion kinetics can improve ZIB electrochemical performance.Herein,N-doped vanadium oxide(N-(Zn,en)VO)via defect engineering is reported as cathode for aqueous ZIBs.Positron annihilation and electron paramagnetic resonance clearly indicate oxygen vacancies in the material.Density functional theory(DFT)calculations show that N-doping and oxygen vacancies concurrently increase the electronic conductivity and accelerate the diffusion kinetics of zinc ions.Moreover,the presence of oxygen vacancies substantially increases the storage sites of zinc ions.Therefore,N-(Zn,en)VO exhibits excellent electrochemical performance,including a peak capacity of 420.5 mA h g^(-1)at 0.05 A g^(-1),a high power density of more than 10000 W kg^(-1)at 65.3 Wh kg^(-1),and a long cycle life at 5 A g^(-1)(4500 cycles without capacity decay).The methodology adopted in our study can be applied to other cathodic materials to improve their performance and extend their practical applications. | Feng Zhang Min Du Zhenyu Miao Houzhen Li Wentao Dong Yuanhua Sang Hechun Jiang Wenzhi Li Hong Liu Shuhua Wang | 2022 | InfoMat2022，4，11： | 0 |
| 11 | Fabrication and laser output of transparent Nd:YAG ceramics from microwave synthesized precursors显示文摘We report the laser output of transparent Nd:YAG(Nd:Y3Al5O12) ceramics fabricated from Nd:YAG precursors through the microwave-assisted homogenous precipitation(MAHP) method.Pure phase and uniform Nd:YAG nano-powders with average sizes less than 100 nm were obtained by heating treatment of the Nd:YAG precursor particles aged for 6 d in vessel with humidity of 30%-50% at 25°C.Transparent Nd:YAG ceramic pellets were obtained by vacuum sintering at 1730°C for 10 h.Laser output(305 mW) with a slope efficiency of 5.1% was realized through an end-pumped configuration.Our results indicate that the MAHP method could potentially be used for the fabrication of laser ceramic products. | ZHANG Xiaolin LIU Duo WANGJiyang YU Haohai QIN Haiming SANG Yuanhua LIU Hong | 2011 | Rare Metals2011，30，6： | 0 |
| 12 | Synthesis and characterization of lithium niobium borate glasses containing neodymium显示文摘A series of(90–x)Li_2B_4O_7-10Nb_2O_5-xNd_2O_3 glass samples(x=0, 5 mol.%, 10 mol.%, 15 mol.%, 20 mol.% and 25 mol.%) were synthesized using melt quenching technique. X-ray diffraction(XRD), differential thermal analyzer(DTA), Fourier transformed infrared(FTIR), ultraviolet-visible-near-infrared(UV-Vis-NIR) spectrometer and photoluminescence(PL) spectroscopic characterizations were made to examine the influence of Nd3+ concentration on the physical, structural and optical properties. Various physical properties such as glasses density, molar volume, thermal stability, ion concentration, polar on radius, inter-nuclear distance, field strength, cut-off wavelength, energy band gap and Urbach energy were calculated. The samples were amorphous in nature and confirmed from XRD pattern. The FTIR spectra revealed the presence of BO_3 and BO_4 functional groups. UV-Vis-NIR spectra exhibited nine prominent bands centered at 353, 430, 475, 524, 583, 681, 745, 803, 875 nm corresponding to the transitions from the ground state to ~4D_(3/2), ~2P_(1/2), ~2G_(9/2), ~4G_(7/2), ~4G_(5/2), ~4F_(9/2), ~4F_(7/2), ~4F_(5/2), ~4F_(3/2) excited states, respectively. Moreover, the emission spectra at 355 nm excitation displayed three peaks centered at 903 nm(~4F_(3/2)→~4I_(9/2)), 1059 nm(~4F_(3/2)→~4I_(11/2)) and 1333 nm(~4F_(3/2)→~4I_(13/2)), respectively. Fluorescence lifetime was recorded between 53.69 to 28.43 μs. It was found that varying concentration of Nd^(3+) ions strongly affected the physical, structural and optical properties of the glass samples. | W.H.A.Kamaruddin M.S.Rohani M.R.Sahar LIU Hong SANG Yuanhua | 2016 | Journal of Rare Earths2016，34，12： | 0 |
