| 2 | Growth of 12-inch uniform monolayer graphene film on molten glass and its application in PbI2-based photodetector显示文摘Direct growth of large area uniform graphene on functional insulating materials is essential for engineering versatile applications of graphene. However, the existing synthesis approaches can hardly avoid the generation of non-uniform multilayer graphene along the gas flow direction, affording huge challenges for further scaling up. Herein, by exploiting the molten state of soda-lime glass, we have accomplished the direct growth of large area uniform (up to 30 cm × 6 cm) graphene via a facile chemical vapor deposition route on low cost soda-lime glass. The use of molten glass eliminates the chemically active sites (surface corrugations, scratches, defects), and improves the mobility of carbon precursors, affording uniform nucleation and growth of monolayer graphene. Intriguingly, thus-obtained graphene acts as an ideal coating layer for the surface crystallographic modification of soda-lime glass, making it epitaxy substrates for synthesizing high-quality PbI2 nanoplates and continues films. Accordingly, a prototype photodetector was fabricated to present excellent photoelectrical properties of high responsivity (~ 600 on/off current ratio) and fast response speed (18 μs). This work hereby paves ways for the batch production and the direct applications of graphene glass as platforms for constructing high performance electronic and optoelectronic devices. | Zhaolong Chen Haina Ci Zhenjun Tan Zhipeng Dou Xu-dong Chen Bingzhi Liu Ruojuan Liu Li Lin Lingzhi Cui Peng Gao Hailin Peng Yanfeng Zhang Zhongfan Liu | 2019 | Nano Research2019，12，8： | 1 |

| 5 | Strategies from small-area to scalable fabrication for perovskite solar cells显示文摘Recently,perovskite solar cells(PSCs) have flourished,and their power conversion efficiency(PCE) has increased from the initial 3.8% to 25.2% in 2019,which is an unprecedented advance.However,usually high-efficiency and stable PSCs are small-area devices prepared by spin coating.This method is not suitable for the preparation of large-area devices in commercialization.Therefore,there is an urgent need to develop new materials and methods for the scalable fabrication of PSCs.In this review,we first describe the common small-area PSCs preparation methods,understand the nucleation and crystal growth kinetics of perovskite,and analyze the reasons that hinder the development of small-area devices to large-area devices.Next,in order to meet the challenges of PSC’s scalable fabrication,we summarize and analyze four strategies:scaling up precursor solutions,scalable deposition methods for large-area films,scaling up charge-transport layers and back electrodes,developing solar modules.Finally,challenges and prospects are proposed to help researchers prepare high-efficiency large-area PSCs. | Huanhuan Yao Shenghuan Shi Zhizai Li Zhipeng Ci Ge Zhu Liming Ding Zhiwen Jin | 2021 | Journal of Energy Chemistry2021，30，6： | 1 |
| 6 | The concentration quenching characteristics of ~5D_3-~7F_J and ~5D_4-~7F_J (J=0―6) transitions of Tb^(3+) in YBO_3:Tb^(3+) phosphor显示文摘The photoluminescence quenching behaviors of 5D3-7FJ and 5D4-7FJ (J = 0―6) transitions of Tb3+ in YBO3:Tb under 130―290 nm excitation were systematically investigated. The results revealed that the quenching concentrations of both 5D3-7FJ and 5D4-7FJ transitions of Tb3+ in YBO3:Tb were mainly de-pendent on excitation wavelength. Particularly,the quenching concentrations of 5D4-7FJ transitions of Tb3+ under 130―290 nm excitation were correlated with excitation bands of YBO3:Tb. The quenching concentrations of 5D3-7FJ transitions remained at low concentration (2%) under 186―290 nm excitation and then increased gradually with energy of incoming excitation photon when excited at 130―186 nm. This dependence should be involved in their excitation mechanisms and quenching pathway in particular excitation region. | ZHANG JiaChi WANG YuHua ZHANG ZhiYa WANG DeYin CI ZhiPeng SUN YunKui | 2007 | Chinese Science Bulletin2007，52，16： | 1 |

| 9 | Self-luminescence and color-tunable emission in KYb_3F_(10) matrix under different excited sources显示文摘A self-luminescence KYb3 F10 material was obtained via a mild hydrothermal method.Its structure,morphology and the corresponding luminescence properties were studied.There is a self-luminesce nce based on the effective recombination of electron and hole on surface defects or electronic centers in KYb3 F10.The pH values have significant impact on crystallinity and self-luminescent intensity of target products.With the introduction of Tb3+and Eu3+into KYb3 F10 matrix,a series of color-tunable emission can be achieved.Simultaneously,Tb3+and Eu3+can also affect the self-luminescent intensity of host slightly.Although there is no obvious energy transfer between host and activators,Tb3+has a distinct sensitive effect on Eu3+ascribed to the energy transfer between Tb3+and Eu3+.In addition,the thermal stability was carefully investigated,which demonstrate the materials can be as a candidate in fluorescent lamps and displays. | Lili Han Zhijing Zhang Jiang Chen Yirun Zhu Dongcheng Zhu Juan Zhao Wei Shen Zhipeng Ci | 2020 | Journal of Rare Earths2020，38，7： | 0 |
| 10 | Unveiling the origin of performance enhancement of photovoltaic devices by upconversion nanoparticles显示文摘To better utilize the infrared(IR)region in sunlight for photovoltaic devices(PVs),upconversion nanoparticles(UCNPs)have been proposed to improve power conversion efficiency(PCE).However,researchers recently have found that the upconversion(UC)effect is negligible in PVs performance improvement for their ultra-low UC photoluminescence quantum yields of UCNPs solid film,while the real mechanism of UCNPs in PVs has not been clearly studied.Herein,based on the material inorganic perovskitesγ-CsPbI_(3),NaYF_(4):20%Yb^(3+),2%Er^(3+)UCNPs were integrated into different transport layer to optimize device performance.Compared with reference device,the short-circuit current density and PCE of optimized device reached 20.87 mA/cm^(2)(20.39 mA/cm^(2))and 18.34%(17.72%),respectively,without sacrificing open-circuit voltage and filling factor.Further experimental characterizations verified that the improved performance was attributable to enhanced visible light absorption instead of IR.To theoretically explain the statement,the light field distribution in device was simulated and the absorption in different layers was calculated.The results revealed that the introduction of UCNPs with different refractive index from other layers caused light field disturbance,and improved visible light captured by γ-CsPbI_(3).Importantly,through experiments and theoretical calculation,the research deeply explored the potential mechanism of UCNPs in optimizing PVs performance. | Huanhuan Yao Guoqiang Peng Zhizai Li Ge Zhu Wenquan Li Zhipeng Ci Wei Lan Hao Jia Bin Dong Zhiwen Jin | 2022 | Journal of Energy Chemistry2022，31，2： | 0 |
