微乳液法制备ZnS∶Cu纳米微粒及其光学性能的表征

Optical Characterization of Copper-doped Zinc Sulfide Nanoparticles Synthesized in Microemulsion

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

WT5BZ]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
