The thermoluminescence (TL) and emission of coloured RbCl and RbCl:Sn crystals are studied in the temperature range 300 to 560 K. The glow peaks responsible for F centres and tin centres in different valence states are identified using optical bleaching studies. The glow peaks are analysed using total curve fitting method and the kinetic parameters are determinet. In moderately γ‐irradiated tin‐ doped RbCl crystals, the TL emission bands observed at 4.0, 3.6, and 2.2 eV are attributed to Sn 0 , Sn + , and Sn − centers, respectively. A comprehensive energy level diagram depicting the various TL processes in these undoped and tin‐ doped RbCl crystals is proposed.
