摘　　要：卤化铅钙钛矿量子点(LHP-QDs)具有卓越的光电特性,已成为材料科学领域的研究热点。然而,由于LHP-QDs的稳定性不足,易受环境中水分、氧气、光照、热等因素影响,限制其在各种领域中的广泛使用。因此,为改善LHP-QDs的稳定性,推广这类材料的实际应用,本文首先简要介绍了LHP-QDs的制备方法,主要有热注射法、配体辅助沉淀法、原位制备法等;然后,总结了提高LHP-QDs稳定性的研究现状,包括表面配体钝化、离子掺杂和表面包覆等;最后,对提高LHP-QDs稳定性的发展方向进行了展望。Lead halide perovskite quantum dots(LHP⁃QDs)have become one of the research hotspot in materials science due to their excellent photoelectric properties.However,due to the insufficient stability of LHP⁃QDs,they are susceptible to water,oxygen,light,heat and other factors in the environment,which severely limits their widespread use in various fields.Therefore,in order to improve the stability of LHP QDs and promote their practical applications,this paper first briefly introduces the preparation methods of LHP⁃QDs,including hot injection,ligand⁃assisted reprecipitation,in situ preparation and so on.Then,the research status of improving the stability of LHP⁃QDs is reviewed,including surface ligand passivation,ion doping and surface coating.Finally,the development direction of improving the stability of LHP⁃QDs is prospected.
