摘要：
It was carried out the investigation of optical absorption of magnesium-aluminum spinel (MgAl2O4) crystals. The crystals were grown by horizontal directional crystallization method in molybdenum crucible under the protective atmosphere Ar+(CO, H-2). The optical absorption spectra of MgAl2O4 crystals exhibit absorption bands (267 and 325 nm) caused by complexes of defects formed by oxygen vacancies and cations located in anti-sites. It is shown that annealing of crystals in an oxidizing environment at T = 1500 degrees C leads to the elimination of these absorption bands and the improvement of the optical properties of the grown crystals.
