配位型亚铜卤化物发光材料与器件研究进展OA

The new generation of light-emitting devices requires luminescent materials to possess advantages such as high photoluminescence quantum yield,broadly tunable spectra,excellent solution processability,readily accessible raw materials,and environmental friendliness.However,high-performance lead halide perovskites and cadmium-based quantum dots currently pose threats to human health,necessitating the development of low-toxic luminescent materials with comparable performance.Coordinated copper halides represent a class of luminescent materials for novel display and lighting applications.Among lead-and cadmium-free metal halide emitters,they demonstrate leading luminescence properties,positioning them as strong competitors to lead halide perovskites and cadmium-based quantum dots in the field of light-emitting devices.In recent years,significant progress has been made in the research of coordination-type copper(I)halide luminescent materials.Researchers have designed and synthesized a series of coordinated copper halides with diverse ligands and inorganic units,achieving tunable photoluminescence across the visible spectrum and photoluminescence quantum yields approaching unity.Electroluminescent devices based on coordinated copper halides have realized external quantum efficiencies up to 23.5%and maximum luminance exceeding 60 000 cd·m-2,demonstrating considerable application potential.This review summarizes the crystal structures,synthesis methods,and photophysical properties of coordinated copper halides,and discusses their advancements in electroluminescent devices.Finally,the structures,properties,and applications of coordinated copper halides are concluded and future perspectives are provided.
