MoO_3纳米粒子水溶胶的制备与光致变色性质研究

Study of Preparation and Photochromism of MoO_3 Nanoparticles Hydrosol

采用沉淀法制备了MoO3 纳米粒子水溶胶,对制备水溶胶的条件进行了系统地研究。TEM 分析表明,MoO3纳米粒子呈球形,粒径约为60nm, 粒度分布均匀;ED 分析表明,MoO3 纳米粒子为多晶结构。UV-VIS 分析表明,MoO3 纳米粒子水溶胶具有一定的光致变色特性。

MoO3 hydrosol was prepared by precipitation method. The effect factors on hydrosol were discussed systematically. TEM photos show that the MoO3 nanoparticles are spherical in shape, the size is about 60 nm, particle size distribution is in narrow range. ED images indicate that the MoO3 nanoparticles are polycrystalline structure. UV-VIS analysis show that the MoO3 nanoparticles hydrosol had good photochromic effect.
