Abstract

Non-isothermal relaxation techniques in the form of thermally stimulated luminescence phenomena and processes have been utilised to understand the mechanisms involved in the occurrence of luminescence emission during the formation and subsequent destabilisation (by thermal annealing) of the radiation induced and stabilised defects in pure and doped alkali halide crystals. Techniques like thermally stimulated luminescence (TSL) spectra, monochromatic thermoluminescence (MTL) glow curves, photo-stimulated thermoluminescence (PSTL) glow curves have been successfully utilised in this study. Effects of pre-and post-deformation on the X-irradiated crystals on the above luminescence manifested properties have also been studied.
