IMPURITIES AND THERMOLUMINESCENCETitanium-related defects in Lif : Mg, Ti

Abstract
Electron spin resonance (esr) and ionic conductivity have been used to define the possible defect states of Ti in LiF. The esr spectrum shows lines due to specific equilibrium defect complexes containing Ti3+ and F centers, and a broad line due to Ti3+ in a precipitate phase. No Ti2+ ions are observed. Possible interactions between Mg and Ti-related defects are discussed and related to the TL mechanism in LiF
