Preparation and structural characterization of organic-inorganic layered perovskite-type (C12 H25 NH3) 2 PbI4 crystals and thin films

介绍了有机/无机类钙钛矿(C12H25NH3)2PbI4的晶体和薄膜的制备,并采用了XRD、SEM、AFM和PL表征材料的结构、形貌及光学特性等.XRD实验表明制备的(C12 H25NH3)2PbI4晶体结晶度高.探索旋涂法制备工艺参数对薄膜结构的影响,在薄膜XRD中几乎只能观察到(0021)晶面的衍射峰,表明有机/无机类钙钛矿层沿平行与基片方向择优生长,SEM和AFM表明薄膜致密性较好,表面粗糙度较小.
