TL and PL Study of beta irradiated calcite collected from Semaria mines of C.G. Basin

The present paper reports the photoluminescence (PL) and thermoluminescence (TL) studies of natural calcite collected from Semaria mines of C.G. Basin. The sample was irradiated with Sr-90 beta source given a dose of 10Gy and the heating rate used for TL measurements are 6.660C/sec was described. The sample displayed a good TL peak at 1270C and the corresponding activation energy (E) values are calculated. Photoluminescence excitation spectrum at ~254 nm, the corresponding emission spectrum peak at 395 nm is reported.
