ＥＳＲ实验表明Ａｇ在ＺｎＳ微晶中是以Ａｇ＋离子的形式存在．没有测到Ａｇ２＋离子的信号．以Ｍｎ２＋为探针的ＥＳＲ和Ｘ射线衍射分析研究发现．在ＺｎＳ微晶由立方点阵（β相）变为六角点阵（α相）的结构相变中，Ａｇ＋离子对相变的影响与掺杂浓度和煅烧温度有关．当掺Ａｇ量为５×１０－４ｇ／ｇ时相变在１１００～１２００℃出现逆转现象．由Ｍｎ２＋的ＥＳＲ谱得出α相的朗德因子ｇ为２．００６，越精细常数ａ为６．７６ｍＴ，β相的ｇ为２．００２，ａ为６．８１ｍＴ． ESR experiments show that Ag is present in the form of Ag + ions in ZnS crystallites. No signal of Ag2 + ions was detected. ESR and XRD analysis with Mn2 + as probe. In the phase transition of ZnS crystallites from cubic lattice (β phase) to hexagonal lattice (α phase), the influence of Ag + ions on the phase transition is related to the doping concentration and the calcination temperature. When the amount of Ag doping is 5 × 10-4g / g, the phase transition occurs at 1100-1200 ℃. From the ESR spectrum of Mn2 +, the lanthanon g of the α phase was 2.006, the finer constant a was 6.76 mT, the g of the β phase was 2.002 and the a was 6.81 mT.
