摘要:

金属卤化物钙钛矿(MHP)在发光二极管、太阳能电池、激光器、光电探测器、晶体管等众多应用中已成为一种有前途的候选材料。这与其优异特性的协同作用有关,包括高光致发光量子产率、窄且可调谐的发射、长载流子寿命、宽吸收光谱以及高消光系数,还有其他的然而,主要的瓶颈是MHP在环境条件下的稳定性差。这严重限制了其工业化应用和商业化。本文综述了近年来金属氧化物(MOx)复合材料的制备方法、性能增强、表征技术、性能评价方法、性能表征方法等方面的研究进展,并展望了MOx复合材料的应用前景。特别是首次报道了MHPs@MOx复合材料的制备新方法和新应用。这是由对当前MHP稳定性问题的批判性展望和确保MHP @MOx光明未来的进一步方向所决定的

英文摘要:

Metal halide perovskites (MHPs) have become a promising candidate in a myriad of applications, such as light-emitting diodes, solar cells, lasing, photodetectors, photocatalysis, transistors, etc. This is related to the synergy of their excellent features, including high photoluminescence quantum yields, narrow and tunable emission, long charge carrier lifetimes, broad absorption spectrum along with high extinction absorptions coefficients, among others. However, the main bottleneck is the poor stability of the MHPs under ambient conditions. This is imposing severe restrictions with respect to their industrialized applications and commercialization. In this context, metal oxide (MOx) coatings have recently emerged as an efficient strategy towards overcoming the stabilities issues as well as retain the excellent properties of the MHPs, and therefore facilitate the development of the related devices stabilities and performances.This review provides a summary of the recent progress on synthetic methods, enhanced features, the techniques to assess the MHPs-MOxcomposites, and applications of the MHPs@MOx.Specially, novel approaches to fabricate the composites and new applications of the composites are also reported in this review for the first time. This is rounded by a critical outlook about the current MHPs stability issues and the further direction to ensure a bright future of MHPs@MOx
