Abstract

The 3D beta-In2S3 flowerlike architecture assembled from nanoflakes was prepared via a novel complex-precursor assisted (CPA) solvothermal route. The as-prepared beta-In2S3 powder was characterized by X-ray diffraction pattern (XRD), X-ray photoelectron spectra (XPS), transition electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), ultraviolet-visible light (UV-vis) spectra, and photoluminescence spectrum. The novel 3D beta-In2S3 nanostructure exhibit a strong quantum confinement effect. FT-IR spectra were used to investigate the coordinative chemical effect in the complex. A possible mechanism was discussed.

摘要

通过一种新型的复合前驱体辅助（CPA）溶剂热法制备了由纳米片组装而成的三维β-In2S3花状结构。采用X射线衍射图谱（XRD）、X射线光电子能谱（XPS）、透射电子显微镜（TEM）、场发射扫描电子显微镜（FE-SEM）、紫外-可见光（UV-vis）光谱和光致发光光谱对所制备的β-In2S3粉末进行了表征。新型的三维β-In2S3纳米结构表现出很强的量子限域效应。利用傅里叶变换红外光谱（FT-IR）研究了复合物中的配位化学效应。并讨论了一种可能的机理。
