Abstract

For laser phosphate glasses activated by pairwise neodymium and cerium ions, a number of radiation-optical effects have been studied: thermal and thermoradiative decolorization in the region of 200-800 nm; jump-like switching of the valence of cerium ions during the valencecoordination change in its oxygen environment. A new conceptual approach is proposed to the mechanism of the thermoradiation effect of gamma irradiation at temperatures of 100- 400 C, leading to the detection of neodymium-neodymium and neodymium-cerium ion-ion coordination interactions in nano-structural complex complexes involving the structure of a glass matrix, Only thermoradiation exposure.
