摘要/Abstract

摘要： 采用简单的水热法合成了ZnS:Mn微球.利用X射线衍射(XRD)、扫描电子显微镜(SEM)、紫外可见吸收光谱(UV-vis)和光致发光谱(PL)等测试手段对其形貌、结构和光学性质进行了分析.结果表明:ZnS:Mn微球为立方闪锌矿型ZnS结构,且球体由纳米级小微粒组装而成;样品的发光强度随着Mn2+掺杂浓度的增加而增强,当浓度为3%时达到最大值,进而发生了浓度淬灭现象.

Abstract: ZnS:Mn microspheres were synthesized by a simple hydrothermal method .The crystal structure , morphology , composition and optical property of the samples were characterized by X-ray diffraction ( XRD ) , scanning electron microscopy ( SEM ) , UV-vis absorption spectrum and photoluminescence spectrum ( PL) .The results show that ZnS:Mn microspheres have a cubic zinc blend crystal structure , and microspheres comprised of nanoparticles .Besides , it is found that the PL intensity of ZnS:Mn microspheres obviously increases with the concentration of Mn and reaches maximum at 3%because of concentration quenching of Mn 2+.

Key words: hydrothermal method;ion doping;ZnS:Mn;photoluminescent property
