摘要:

?采用溶液法合成甲胺溴铅(CH3NH3PbBr3)多晶原料,用溶液蒸发法生长了尺寸约为7 mm?7 mm?3 mm的CH3NH3PbBr3晶体。测量了晶体的XRD谱,采用X射线外推法研究了晶体结构。结果表明:生长的CH3NH3PbBr3单晶为立方晶系结构,晶格参数a=0.592 76(7)  nm。将微型溶液晶体生长装置与荧光共聚焦显微镜相结合,实时观测了不同生长条件下CH3NH3PbBr3晶体的微观形貌和不同晶面的生长速率。得到(011)、(101)和(001)晶面的平均水平生长速率分别为0.017 57(6)、0.021 44(4)和0.018 65(7) nm/s;发达晶面簇为{110}和{100}。

 Polycrystalline methylamine bromine lead (CH3NH3PbBr3) for crystal growth was synthesized by a solution method. CH3NH3PbBr3 single crystals with the size of 7 mm?7 mm?3 mm were grown by a solution evaporation method. The crystal structure was determined by X-ray diffraction. The results show that the grown CH3NH3PbBr3 crystal belongs to a cubic system structure with the lattice parameter of a=0.592 76 nm(7). The microstructures and the growth rates of different crystal faces of CH3NH3PbBr3 crystal under different conditions were determined by a micro-solution crystallizer with a fluorescence microscope. The average horizontal growth rates of the crystal faces (011)、(101) and (001) determined are 0.017 57(6) nm/s, 0.021 44(4) nm/s and 0.018 65(7) nm/s, respectively, and the {110} and {100} faces are well-developed for CH3NH3PbBr3 crystal.
