概要
- 論文の詳細を見る
Afterglow emission and Thermoluminescence are observed on UV-irradiated MgO powders at low temperatures of 140 K-300 K under high vacuum. The main peak of the TL spectrum is at 3.1 eV with a shoulder at about 2.3 eV. A plausible emission process is discussed in terms of the tunneling recombination of an electron of F_s^+ centers and a hole of V_s^- centers on the surfaces. The luminescence is quenched by O_2 gas exposure at low temperature.
