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.
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.
