Study of Preparation and Photochromism of MoO3 Nanoparticles Hydrosol

摘要:

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.

Abstract:

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.
