| Summary: | Title screen Optical absorption of polycrystalline corundum (polycor) after irradiation with iron ions and subsequent annealing in vacuum was studied. It was found that substitutional, intrinsic radiation, biographical defects, and complexes on their basis have an effect on the absorption parameters and optical transitions between localized states and allowed bands. The contributions to changes in the optical properties of individual substitutional defects, their clusters, and complexes with the participation of substitutional defects and radiation defects were singled out. The influence of defects and iron oxides formed upon annealing on absorption was estimated. The most proable nature of clusters of substitutional defects and impurity-vacancy complexes was identified. Режим доступа: по договору с организацией-держателем ресурса |
