外束离子感生发光法及其应用研究初探

Study on External Beam Ionoluminescence and Its Primary Application

摘要: 基于外束质子激发Ｘ荧光分析（ＰｒｏｔｏｎＩｎｄｕｃｅｄＸｒａｙＥｍｉｓｓｉｏｎ———ＰＩＸＥ法）的外束离子感生发光（ＩｏｎＢｅａｍＩｎｄｕｃｅｄＬｕｍｉｎｅｓｃｅｎｃｅ，ＩＢＩＬ）实验装置，实现了ＩＢＩＬ对地质样品斜长石（钙长石）中元素铁的化学价态的直接分析。实验结果表明，Ｆｅ２＋和Ｆｅ３＋光谱峰分别位于５５３ｎｍ和６８２ｎｍ清晰分离，Ｆｅ３＋光谱峰清晰突出，Ｆｅ２＋峰也可确认

Abstract: facility for detection of ionoluminescence(IL) induced by a 2.4 MeV external proton beam was developed. In order to offer useful information about the chemical properties of atoms in crystals, chemical valence states of iron in a plagioclase were directly
