Extrinsic Defects in UV-irradiated MgO Single Crystal Detected by Thermoluminescence

D. Kadri, S. Hiadsi and S. Hamzaoui

Abstract:
MgO single crystal sample previously irradiated with ultraviolet light (UV) 4.8 eV has been studied using thermoluminescence (TL) technique in the temperature range 170-500°K, in this study, we were mainly interested in the extrinsic defects (impurities), these impurities are localised in four distinct regions, Cr3+ is assigned to the first region 680-760 nm, in the second region 465-500 nm we find Ni2+, Fe3+ is localised in the third region 310-375 nm and lastly the Ca2+ and K+ have been found to emit in the 180-260 nm region.
