Investigation on Comparative Optical Absorption and Luminescent Property of Cerium Doped Potassium Halide Single Crystals
The comparison of Optical absorption, Photoluminescence (PL), Thermoluminescence (TL) and other optical studies of X-ray irradiated Ce 3+ doped KBr and KI single crystals were discussed. Photoluminescence of these crystals exhibits characteristic Ce 3+ emission due to 5d-4f transition in both the studied material in addition to the host emission. Optical absorption and PL studies confirm the presence of Cerium ions in the trivalent state in both KBr and KI host .The characteristic emission due to Ce 3+ ions in the spectral distribution under optically stimulated emission and TL emission confirms the participation of Cerium ions in the recombination process in both host material. Trap parameters for the TL process are calculated and compared.
