基　　金：the National Key Research and Development Plan of China(No.2019YFE0107200);the National Natural Science Foundation of China(Grant No.11705277),the Natural Science Foundation of Hubei Province(No.2020CFB700);the Doctoral Research Foundation Project of Hubei University of Arts and Science(No.kyqdf2020023);Innovation Research Team Project of Hubei University of Arts and Science(No.2020kypytd001). 摘　　要：The broad emission and high photoluminescence quantum yield of self-trapped exciton(STE)radiative recombination emitters make them an ideal solution for single-substrate,white,solid-state lighting sources.Unlike impurities and defects in semiconductors,the formation of STEs requires a lattice distortion,along with strong electron–phonon coupling,in low electrondimensional materials.The photoluminescence of inorganic copper(Ⅰ)metal halides with low electron-dimensionality has been found to be the result of STEs.These materials were of significant interest because of their leadfree,all-inorganic structures,and high luminous efficiencies.In this paper,we summarize the luminescence characteristics of zero-and one-dimensional inorganic copper(I)metal halides with STEs to provide an overview of future research opportunities. 关键词：self-trapped exciton(STE) low electrondimensional inorganic copper(Ⅰ)metal halides
