TL and PL Study of beta irradiated calcite collected from Semaria mines of C.G. Basin
Journal Title: Journal of Atoms and Molecules - Year 2012, Vol 2, Issue 4
Abstract
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.
