摘要: 用电子自旋共振(ESR)方法对非晶Ag+离子导体0.85AgI~0.15Ag4P2O7的热处理晶化过程进行研究,在样品中掺入微量(约1×10-3 g/g)的Mn2+或V4+离子作为自旋探针离子,它们的ESR谱强度随升温线性减弱,当样品完全晶化时ESR谱消失。这样测定的样品完全晶化的温度分别为98℃(掺Mn的)和108℃(掺V的).本文还对Mn2+和V4+的ESR谱进行了分析。

Abstract: Crystallization of amorphous Ag+ ionic conductor 0.85AgI~0.15Ag4P2O7 was studied by Electron-Spin-Resonanee(ESR).The samples were doped with trace amount Of Mn+2 or V+4 as spin probe ions and their concentrations are about 10-3 gram/gram in each sample,their ESR spectra intensities are weakened linearly with the increase of temperature,and the ESR signal disappears when the sample is completely crystallized.Thus the final crystallization temperatures are 98℃ for Mn-doped and 108℃ for V-doped conductors.The ESR spectra of Mn+2 and V+4 are analysed.

Key words: ESR, Ag+ ionic conductor, Crystallization of amorphous materials
