RADIATION-OPTICAL AND THERMO-RADIATION PHENOMENA IN LASER PHOSPHATE GLASSES COACTIVATED WITH NEODIMIUM AND CERIUM OXIDES

E.M.Ibragimova, .K.Salakhitdinova, .N.Salakhitdinov, .A.Yusupov


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.
