Abstract
Abstract Thermoluminescence (TL) or natural chalcopyrite (CuFeS2) obtained from Mosabani Copper Mines shows two glow peaks at 198 and 250°C upon X-irradiation at room temperature. But the quenched sample when X-irradiated shows four glow peaks at 86, 136, 198 and 250°C. The emission spectra of all the glow peaks show a prominent band with a maximum at 566 nm. Both thermal and anomalous fading were observed in quenched samples. Tentative explanations for emission spectra and anomalous fading are given.
