Description

The thermoluminescence (TL) peak in natural sodalite near 230 oC, which appears only after submitted to thermal treatments and to gamma irradiation, has been studied in parallel with electron paramagnetic resonance (EPR) spectrum appearing under the same procedure. This study revealed a full correlation between the 230 oC TL peak and the eleven hyperfine lines from EPR spectrum. In both case, the centers disappear at the same temperature and are restored after gamma irradiation. A complete model for the 230 oC TL peak is presented and discussed. In addition to the correlation and TL model, specific characteristics of the TL peaks are described.
