化学合成法制备ZnS∶Cu纳米荧光粉研究

Study on Preparation of Cu Doped ZnS Nano-phosphor Powder by Chemical Synthesis

本文介绍一种制备ZnS∶Cu纳米荧光粉的化学合成方法。本方法中 ,通过调节巯基乙酸与甲基丙烯酸的摩尔比 ,可得到不同粒径的纳米荧光粉。用TEM ,XRD和PL谱对所制得的纳米荧光粉进行了表征。

In this paper,we described a new method for preparation of Cu doped ZnS nano phosphor powder. The size of the particles can be easily controlled by adjusting the molar ratio of the mercaptoacetic acid to monomer of the methacrylic acid. The transmission electron microscope (TEM),X ray powder diffraction (XRD) and photoluminescence (PL) are used to characterize the structure of this nanopowder.The chemical synthesis method can be easily extended to prepare other metal doped ZnS nanopowder.
