摘要

利用微乳液法制备出ZnS:Cu纳米微粒。XRD表明微粒粒径为3～5nm,且为立方晶型结构。在紫外吸收光谱中,ZnS:Cu纳米微粒吸收峰蓝移。发射光谱表明ZnS:Cu纳米微粒产生一个位于482nm的绿色发射带。

Abstract

ZnS:Cu nanoparticles were prepared in microemulsion at room temperature.X-ray diffraction analysis shows that the diameter of the particles is 3~5nm and the particles are cubic crystallites structure.Ultraviolet absorption demonstrates the increased bandgap due to quantum confinement.A green emission band at 482nm can be observed in PL spectrum.
