Abstract :
Defect formation in BaF2 single crystals doped with cadmium is investigated by optical absorption, electron paramagnetic resonance (EPR) and thermoluminescence. An optical absorption band observed in X-irradiated at 295 K crystals CaF2 (at 3.8 eV), SrF2 (at 3.95 eV) and BaF2 (at 4.08 eV) is assigned to absorption of Cd+-ions. In addition, two type hole centers: pure Vk and perturbed Vk-centers, are observed in BaF2–1%CdF2 crystals X-irradiated at 77 K.
