Abstract

CuInZnSe powders with various atomic percentages (x = 0, 0.05, 0.11, 0.16 and 0.21) were synthesized with the solvothermal method using metal chlorides and ethylendiamine as sources of precursors and a solvent, respectively. The experiment aims to investigate the effect of atomic percentages of Zn compounds on the structural and optical properties of CuInZnSe in order to improve future technological applications based on this material. The powders' chalcopyrite phases were identified by X-ray diffraction. Energy dispersive X-ray spectroscopy analysis revealed the presence of Cu, In, Zn and Se with the expected atomic ratio of Zn/(In + Zn). Scanning electron microscopy and transmission electron microscopy analysis showed that the powders have large-scale desert rose-like structures. The nanopowders' optical study by UV-visible spectrophotometry showed that the CuInZnSe energy gap values increase with the molar fraction of Zn. A change from 1.15 to 1.4 eV was observed.

摘要

采用溶剂热法，分别以金属氯化物和乙二胺作为前驱体源和溶剂，合成了具有不同原子百分比（x = 0、0.05、0.11、0.16和0.21）的CuInZnSe粉末。该实验旨在研究锌化合物的原子百分比对CuInZnSe结构和光学性质的影响，以便改进基于这种材料的未来技术应用。通过X射线衍射确定了粉末的黄铜矿相。能量色散X射线光谱分析揭示了铜、铟、锌和硒的存在，其锌/（铟 + 锌）的原子比符合预期。扫描电子显微镜和透射电子显微镜分析表明，这些粉末具有大规模的沙漠玫瑰状结构。通过紫外可见分光光度法对纳米粉末进行的光学研究表明，CuInZnSe的能隙值随锌的摩尔分数增加而增大。观察到能隙值从1.15 eV变为1.4 eV。
