4Effects of Mg Incorporation on Microstructure and Optical Properties of ZnO Thin Films Prepared by Sol-gel Method显示文摘Well-crystallized MgZnO alloy thin films with hexagonal wurtzite structure were fabricated by sol-gel method. With the band gap increases, the surface roughness and the grain size reduces. It is worth noting that the intensity of the band-edge luminescence of Mg doped films enhances with the increase of the Mg content. The microstructure and photoluminescence mechanism have been discussed based on X-ray diffraction patterns, atomic force microscopy images, ultraviolet-visible absorption spectra, photoluminescence spectra and Fourier transform infrared spectra.Rui Ding Chunxiang Xu Baoxiang Gu Zengliang Shi Haitao Wang Long Ba Zhongdang Xiao 2010Journal of Materials Science & Technology2010,26,7:1
5High-performance self-powered ultraviolet to near-infrared photodetector based on WS_(2)/InSe van der Waals heterostructure显示文摘van der Waals heterostructures(vdWHs)based on two-dimensional(2D)materials without the crystal lattice matching constraint have great potential for high-performance optoelectronic devices.Herein,a WS_(2)/InSe vdWH photodiode is proposed and fabricated by precisely stacking InSe and WS_(2)flakes through an all-dry transfer method.The WS_(2)/InSe vdWH forms an n–n heterojunction with strong built-in electric field due to their intrinsic n-type semiconductor characteristics and energy-band alignments with a large Fermi level offset between WS_(2)and InSe.As a result,the device displays excellent photovoltaic behavior with a large open voltage of 0.47 V and a short-circuit current of 11.7 nA under 520 nm light illumination.Significantly,a fast rising/decay time of 63/76μs,a large light on/off ratio of 105,a responsivity of 61 mA/W,a high detectivity of 2.5×10^(11) Jones,and a broadband photoresponse ranging from ultraviolet to near-infrared(325–980 nm)are achieved at zero bias.This study provides a strategy for developing high-performance self-powered broadband photodetectors based on 2D materials.Jinping Chen Zhen Zhang Yi Ma Jiying Feng Xiaoyu Xie Xiaoxuan Wang Aoqun Jian Yuanzheng Li Zhuxin Li Heng Guo Yizhi Zhu Qiannan Cui Zengliang Shi Chunxiang Xu 2023Nano Research2023,16,5:1
6Nano-buffer controlled electron tunneling to regulate heterojunctional interface emission显示文摘Interface emission from heterojunction is a shortcoming for electroluminescent devices.A buffer layer introduced in the heterojunctional interfaces is a potential solution for the challenge.However,the dynamics for carrier tunneling to control the interface emission is still a mystery.Herein,the low-refractive HfO_(2)with a proper energy band configuration is em-ployed as the buffer layer in achieving ZnO-microwire/HfO_(2)/GaN heterojunctional light-emitting diodes(LEDs).The optic-ally pumped lasing threshold and lifetime of the ZnO microwire are reduced with the introduced HfO_(2)layer.As a result,the interface emission is of blue-shift from visible wavelengths to 394 nm whereas the ultraviolet(UV)emission is en-hanced.To regulate the interface recombination between electrons in the conduction band of ZnO and holes in the valence band of GaN,the tunneling electrons with higher conduction band are employed to produce a higher tunneling current through regulation of thin HfO_(2)film causing blue shift and interface emission enhancement.Our results provide a method to control the tunneling electrons in heterojunction for high-performance LEDs.Wei Liu Zhuxin Li Zengliang Shi Ru Wang Yizhi Zhu Chunxiang Xu 2021Opto-Electronic Advances2021,4,9:1
7Design of tooth color measurement system based on silicon double P-N junction color sensor显示文摘Working principles of silicon double P-N junction color sensor are introduced and a color measurement system to distinguish tooth color difference is designed in this paper.This system consists of silicon double P-N junction,a small optical fiber probe,signal process circuit and an MSP430FG439 single-chip system.Small in size,this system can measure different parts of the tooth in a fast and convenient way with high-accuracy.Thus,this system will be very promising in building prosthodontics and tooth fabrication.Zengliang SHI Dali LIU Yu WANG Xi CHEN Shiying BAI Jingwei XU 2009Frontiers of Electrical and Electronic Engineering in China2009,4,3:0
8SERS-encoded nanocomposites for dual pathogen bioassay显示文摘Surface-enhanced Raman spectroscopy(SERS)has been successfully applied to detect various biomolecules,but it is still in challenge to assay living cells or bacteria sensitively,selectively and quantitatively in complex environments.In this paper,4-ATP and DTNB are assembled on Ag nanoparticle(NP)-decorated poly(styrene-co-acrylic acid)(PSA)nanospheres and then sealed by silica shells to form sensitive SERS labels based on the localized surface plasmon resonance of Ag NPs and large light scattering cross-sections of PSA nanospheres.They are further developed as encoding tags for dual detection of S.aureus and E.coli after assembling corresponding aptamers,which demonstrate ultralow detection limits of 8 cell L-1 for S.aureus and 2 cell L-1 for E.coli.Such a bioassay indicates a point-of-care strategy of ultrasensitively biomedical detections by encoding specific SERS tags.Yaqi Shan Mingliang Wang Zengliang Shi Milan Lei Xiaoxuan Wang Fu-Gen Wu Huan-Huan Ran Gowri Manohari Arumugam Qiannan Cui Chunxiang Xu 2020Journal of Materials Science & Technology2020,36,8:0
9Spatiotemporal sectioning of two-photon fluorescence ellipsoid with a CsPbBr_(3) nanosheet显示文摘Two-photon fluorescence (TPF) ellipsoid formed by a focused femtosecond laser into luminescent media serves as a fundamental pixel for TPF spatiotemporal imaging. Visualizing spatiotemporal evolution of the TPF ellipsoid itself in a selected luminescent medium is important for correctly reconstructing and interpreting spatiotemporal information of imaged targets. Here, we report a new spatiotemporal sectioning technique with a luminescent CsPbBr_(3) nanosheet and visualize the spatiotemporal evolution of TPF ellipsoid along the axial direction. Time-resolved axial lengths of TPF ellipsoids turn out to broaden nonlinearly with a turning point at about 600 ps. By comparison experiments, observed phenomena are attributed to photocarrier trapping and TPF photon recycling processes within CsPbBr_(3) nanosheets. The spatiotemporal sectioning technique is expected to be widely applicable, which will ignite a plethora of investigations and applications utilizing TPF ellipsoid.Yizhi Zhu Jinping Chen Qiannan Cui Heng Guo Zhuxin Li Zengliang Shi Chunxiang Xu 2021Nano Research2021,14,11:0
