TL glow of γ‐irradiated crystals shows a single peak at 380 K. On F‐light bleaching a new peak attributable to Z 1 ‐centres appears around 355 K. The presence of OH − reduces the TL glow. The characteristic emission of the impurity is observed at 3.65 eV. The irradiated crystals show the presence of the “O 2− –vacancy” complex. The TL process is due to the thermal release of F‐electrons.
