EPR and TL studies of phenakite crystal and application to dating

Mechanisms of TL for production of the 230°C peak in natural sodalite

“…Its optical absorption, dielectric relaxation phenomena, as well as EPR spectra are studied in some detail by several workers, reference to which can be found in the recent paper of Cano et al [2]. However, no serious attempt has been made to study its TL in spite of the fact that TL of other silicates minerals are studied by a large number of workers [3][4][5][6][7][8][9].…”
