摘要：

基于外延异质结构的有机-无机杂化钙钛矿/二维纳米片复合材料在光电领域具有很好的应用前景,但目前使用的固相制备方法大大限制了这一目标的实现.我们通过精细调节溶剂环境,成功利用外延沉积的方式实现了在三角/六方相MoS2纳米片表面生长立方相MAPbBr3（MA=CH3NH+3）钙钛矿纳米晶.虽然MAPbBr3与MoS2存在较大的晶格不匹配度,但是由于MoS2纳米片性质柔软且表面缺失悬挂键,可以在两条不同方向上观察到较高容忍度（～1%错位）的外延生长关系.这种外延界面的形成有利于MAPbBr3与MoS2之间有效的能量转移,因此基于MAPbBr3/MoS2异质结的纸质器件与MAPbBr3或MoS2器件相比具有更优异的光电性能.此外,除了提高光吸收能力和能量传递, MoS2纳米片的存在还为离散的MAPbBr3纳米晶提供柔性和连续的基底,从而改善了MAPbBr3纳米晶粒的成膜能力.这种液相外延法可用于高性能的有机无机杂化钙钛矿与二维材料的异质结构材料的大规模制备,将推动异质结构材料在光电领域的广泛使用.
