MncMg1-cO radiation defects thermal stability

Full text: Thermal treatment provides a possibility of the controlled change of optical and durability properties of semiconductors and dielectric materials. The results of study of radiation defects thermal stability in MncMg1-cO (c<0.3) single solid solution are presented. In absorption spectra of irradiated MncMg1-cO apart from absorption bands due to transitions from ground state to the excited states in manganese ions there are also the bands associated with radiation defects. At temperature higher than 700 K two wide bands ∼26000 cm-1 and ∼20000 cm-1 appear in absorption spectra. It is shown that the radiation defects thermal stability in MncMg1-cO (c<0.3) single solid solution are distinguished from that in pure magnesium oxide crystals. The mechanisms of band formation and the radiation defects thermal stability distinction of MncMg1-cO (c<0.3) single solid solution from pure magnesium oxide crystals are discussed
