Abstract

Zinc sulfide doped with Mn2+ ions was synthesized in a homogeneous dodecane medium using the emerging reagent method. Using the methods of chemical analysis, X-ray powder diffraction, IR spectroscopy, and electron microprobe microscopy, the products were identified and photographs of the surface of powder particles (SEM) were obtained. Based on the results obtained, it was concluded that nano-sized objects are formed that have a polytype structure with a predominance of distorted cubic crystals, forming agglomerates up to 10 μm in size in ZnS powder and up to 100 μm in ZnS–Mn powder. The formation of nanosized ZnS particles is confirmed by spectral data. The influence of manganese ions on the photoluminescence (PL) of the powder manifests itself in a change in the type of the descending branch of the ZnS–Mn PL band; this is associated with recombination processes at the levels of defects formed by Mn2+ ions in the ZnS structure at their low concentration.

基于十二烷的均相体系中硫化锌的合成和掺杂及其鉴定和光学特性
摘要 采用新兴试剂法,在均相十二烷介质中合成了掺杂 Mn2+ 离子的硫化锌。利用化学分析、X 射线粉末衍射、红外光谱和电子显微镜等方法对产物进行了鉴定,并获得了粉末颗粒表面的照片(扫描电镜)。根据所获得的结果,可以得出结论:形成的纳米级物体具有多晶型结构,以扭曲的立方晶体为主,在 ZnS 粉末中形成的团块大小可达 10 μm,在 ZnS-Mn 粉末中可达 100 μm。光谱数据证实了纳米级 ZnS 颗粒的形成。锰离子对粉末光致发光(PL)的影响表现为 ZnS-Mn PL 带下降分支类型的变化;这与低浓度 Mn2+ 离子在 ZnS 结构中形成的缺陷水平上的重组过程有关。
