Highly sensitive cerium-doped K2SO4phosphor was synthesized for optically stimulated luminescence (OSL) properties. The present study mainly investigated various kinetic parameters and correlation between the thermoluminescence and OSL (TL-OSL) processes. Continuous wave-OSL sensitivity of the phosphor is four times more than that of Al2O3:C (Landauer). The phosphor exhibits good TL-OSL correlation. Most of the charge carriers in K2SO4:Ce get depleted using optical stimulation which confirms their participation in TL as well as OSL processes. Optical bleaching also affects the order of kinetics for TL. The glow curve of K2SO4:Ce without illumination exactly fits with two components, whereas it is fitted with three components when optically bleached for 60 s. Bleaching also shifted the glow peaks toward higher temperature side indicating non- first-order kinetics.
