摘　　要：防伪与国家安全、社会和谐以及经济稳定息息相关。其中,钙钛矿量子点因具有高荧光量子效率以及可调的发光波长而被广泛应用,然而其稳定性差不利于防伪应用。系统介绍了提高金属卤化物钙钛矿量子点载流子传输特性和稳定性的研究动态,并结合影响钙钛矿量子点稳定性的因素,总结了提高钙钛矿量子点材料稳定性的主要策略,如修饰疏水配体、构建半导体/钙钛矿量子点异质结、包覆聚合物、开发非铅全无机组分等,进一步为稳定、高效荧光防伪材料的开发提供参考。Anti-counterfeiting is closely related to national security,social harmony and economic stability.Among them,perovskite quantum dots(QDs)have been widely used due to their high fluorescence quantum efficiency and adjustable light wavelength,but their poor stability is not conducive to anti-counterfeiting applications.The research progress of improving carrier transport characteristics and stability of metal halide perovskite QDs was systematically introduced.Considering the influencing factors of perovskite QDs stability,the main strategies to improve it,such as modifying hydrophobic ligands,building semiconductor heterojunction/perovskite QDs,coating polymer,and developing non-lead inorganic components were summarized.Further,it could provide reference for the development of stable and efficient fluorescence anti-counterfei-ting materials.
