金属卤化物钙钛矿纳米晶体因其独特的光电特性,在光伏和光电等领域展现了巨大的应用前景,受到广泛的研究关注。但钙钛矿纳米晶体本身的离子晶体性质使其在水、热等环境下不稳定,从而限制了其实际应用。金属卤化物钙钛矿纳米晶体可以与聚合物结合形成纳米复合材料,具有许多优越的特性。聚合物基体可以赋予复合材料稳定性、可拉伸性和溶液加工性,而纳米晶体可保持其尺寸、形状和组成相关的光电特性。因此,这些纳米复合材料在下一代显示器、照明、传感、生物医学技术和能量转换等领域具有巨大的潜力。本文总结了金属卤化物钙钛矿纳米晶/聚合物纳米复合材料的最新研究进展。首先,讨论了制备金属卤化物钙钛矿纳米晶体/聚合物复合材料的各种合成策略。其次,介绍了金属卤化物钙钛矿纳米晶体/聚合物复合材料在发光二极管、激光和闪烁体等领域的应用。最后,提出了该领域未来的研究方向和挑战。

Metal halide perovskite nanocrystals have attracted extensive research attention due to their unique photoelectric properties,showing great application prospects in photovoltaic and optoelectronic fields.However,due to the ionic crystal properties of perovskite nanocrystals,they are unstable in water,heat and other environments,which limits their practical application.Metal halide perovskite nanocrystals can be combined with polymers to form nanocomposites with many superior properties.Polymer matrix can endow composites with stability,stretchability and solution processability,while nanocrystals can maintain their size,shape and composition-related photoelectric properties.Therefore,these nanocomposites have great potential in the fields of next-generation displays,lighting,sensing,biomedical technology and energy conversion.This paper summarizes the latest research progress of metal halide perovskite nanocrystals/polymer nanocomposites.Firstly,various synthesis strategies for preparing perovskite nanocrystals/polymer composites are discussed.Secondly,the applications of metal halide perovskite nanocrystals/polymer composites in light-emitting diodes,lasers and scintillators are discussed.Finally,the future research directions and challenges in this field are proposed.
