摘　　要：采用溶胶-凝胶法在不同条件下制备了ZnS∶Cu纳米微粒,合成中首次用中性硫代乙酰胺分子对纳米微粒表面进行修饰。所制ZnS∶Cu纳米微粒在紫光灯的照射下,呈现绿色发光现象;在332 nm的紫外光激发下,ZnS∶Cu纳米微粒产生位于516 nm的发射峰;相对于体相材料在462nm的发射峰红移了54 nm;另外,样品的紫外吸收光谱表明,位于290 nm的吸收峰,相对于体相材料蓝移了50.6 nm.ZnS ： Cu nanoparticles were obtained in different conditions by sol-gel method and neutral CH3CSNH2 was used for the first time to modify the nanoparticles. The emission spectrum and UV absorbing spectrum were also measured when excited by ultraviolet radiation of 332 nm, ZnS ： Cu gave off a green band emission at 516 nm,and the bulk ZnS gave off a blue band emission at 462 nm. The green emission band showed obvious red-shift of 54 nm. The UV absorbing peak presents obvious blue-shift of 50. 6 nm.
