摘要: 描述了一种生产ZnS:M[M=Mn,Cu,Cu(Al)]纳米荧光粉的化学合成方法.运用本方法通过调节巯基乙酸与甲基丙烯酸的摩尔比,可在1.8~3.0nm范围内控制纳米粒子的尺寸.选择面积的电子衍射和X射线衍射证明ZnS:M纳米荧光粉具有闪锌矿结构.透射电镜图像表明ZnS:M纳米荧光粉具有较好的尺寸分布.ZnS:Mn的PL谱表明纳米尺寸的ZnS:Mn与体材料相比具有较高的发光效率。

Abstract: A new method for production of ZnS:M[M=Mn, Cu, Cu(Al)] nano-phosphor powders was described. The size of ZnS:M
nanoparcicles can be well controlled from 1.8nm to 3nm by adjusting the molar ratio of mercaptoacetic acid to monomer of methacrylic acid. Selected area
electron diffraction (SAED) and X-ray diffraction (XRD) demonstrate that the ZnS:M nano-phosphor powders have zinc blende crystal structure. TEM image
indicates that the ZnS:M nano-phosphor powders have uniform size distribution. The photoluminescence (PL) of ZnS:Mn reveals that the ZnS:Mn nano-phosphor
powder has greatly luminescent efficiency, compared with bulk ZnS:Mn.

Key words: nano-phosphor powders, ZnS:M
