  ABSTRACT: The present paper reports Thermoluminescence (TL) Glow curve of Mn2+ doped CaAl2O4 phosphor with different UV exposure time. The Glow peak shows general order kinetics and evaluation of kinetic parameters was done by peak shape method. Calculations of Trap Depth were done with Chen’s different methods and order of kinetics, activation energy and frequency factor are calculated. The recorded glow curve shifts towards higher temperature with increasing intensity as a function of UV exposure time until 30 minutes where it is seen that the peak shifts towards low temperature side and intensity also decreases. The peaks were found at 345?C, 356.83?C, 358?C and 356.73?C respectively using the heating rate 6.7?C/s. The PL (photoluminescence) excitation spectra show peaks at 248 nm and 362 nm whereas emission spectra shows peaks between 364 nm and 551 nm. Sample was characterized by XRD technique.
