摘要: 通过简单的生物分子辅助溶剂热法, 成功地合成出了AgInS2微球. 在反应过程中, 生物分子L-半胱氨酸既作为硫源也作为络合剂. 利用X射线衍射(XRD)、能量色散谱(EDS)、X射线光电子能谱(XPS)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等分别对所合成的AgInS2的表面形貌、组成和晶型结构等进行了表征. 结果表明, 所合成的产物为典型的AgInS2正交结构, 平均直径约为2μm. 讨论了不同温度对AgInS2的形成及其形貌的影响, 并根据实验结果对所合成的AgInS2微球可能的形成机理进行了简单的探讨.

Abstract: AgInS2 microspheres were synthesized via a simple solvothermal route using biomolecule L-cysteine-assisted methods. The L-cysteine both as sulfur source and complexing agent plays an important role in the formation of AgInS2 microspheres. The morphology, structure, and phase composition of the as-prepared AgInS2 products were studied through X-ray diffraction, field emission scanning electron microscope, energy dispersive X-ray spectroscope, X-ray photoelectron spectroscope, transmission electron microscope, and high-resolution transmission electron microscope. The Results showed that the as-prepared AgInS2 microspheres were orthorhombic phase with average diameters of about 2 μm. In addition, the effect of reaction temperature on morphology of the product was investigated, and a possible growth mechanism of the AgInS2 microspheres was also determined based on electron microscope.

Key words: AgInS2, L-cysteine, biomolecule, semiconductor
