磷化铟微球的制备、表征及其性能

Synthesis,characterization and optical properties of InP microscopes

以四水合氯化铟和白磷为主要原料,水和二乙烯三胺(DETA)为混合溶剂,通过溶剂热法制备出磷化铟(InP)纳米微球,并用X射线粉末衍射仪和X射线光电子能谱仪对产物的物相和表面元素组成进行了表征,同时用扫描电子显微镜和透射电子显微镜对产物的形貌和尺寸进行了表征.结果表明,所得到的产物为尺寸均一的直径为500nm左右的立方相InP实心微球.为了得到最佳的制备条件,我们还进行了一系列温度和时间的条件实验,最终确定最佳条件为180℃,16h.最后通过紫外-可见分光光度计和荧光分光光度计对产物的光学性能进行了研究.

In this article,InP microscopes were prepared at 180℃ for 16 hours through a sol-vothermal method, InCl3· 4H2O was used as the main raw material, deionized water and D E -TA as the solvent. The as-obtained samples were characterized by X ray powder diffraction （XRD ） and X-ray photoelectron spectroscopy （ XPS ） , Field-Emission Scanning Electron Mi - croscope（FE-SEM ） transmission electron microscopy（TEM） And a series of conditional ex-periments were done. Finally,the photoluminescence（PL） spectrum and photo-catalytic per-formance of InP microscopes were analysized.
