Tin-based Metal Halide Perovskite:Synthesis,Luminescence Performance and LED Applications
摘要
Abstract
Light-emitting diodes(LEDs)are the core components of new display technology and the leader of the new generation of information technology industry.Perovskite light-emitting diodes(PeLEDs),as the latest emerg-ing display technology,have advantages such as high color purity,wide color gamut,simple processing technology,and low cost.PeLEDs are a research hotspot in the field of optoelectronic devices at home and abroad.However,it is necessary to use lead halide perovskites that are harmful to the environment in order to achieve high power conversion efficiency.Among them,tin halide perovskite is the most promising alternative,which has low exciton binding ener-gy and good charge carrier mobility.Due to similar ionic radii and valence states,tin(Sn)can partially or complete-ly replace toxic lead(Pb)to achieve low lead or non-toxic lead halide perovskites.Meanwhile,partial or complete replacement of Pb by Sn will result in new luminescent properties.Although significant progress has been made in improving the optoelectronic properties of Sn based halide perovskites,the parameters of the luminescent devices pre-pared from them are still lower than those of lead-based halide perovskites.This article aims to provide a detailed overview of the research progress and challenges faced in the synthesis,preparation,and optoelectronic properties of Sn based halide perovskites.The relationship between crystal structure and optoelectronic properties is explored.The research progress in the application of Sn based perovskites in electroluminescent devices are reviewed.The fo-cus is on strategies adopted to improve the thin film properties of Sn based perovskite materials to enhance device per-formance.This review provides a reference for the synthesis,luminescent properties,and LEDs applications of tin based metal halide perovskites.关键词
