Abstract
Using synchrotron radiation (SR), radiation relaxation of electron exc itations in nominally pure and anion-imperfect corundum crystals subje ct to irradiation with fast electrons and neutrons was studied. It was found that the luminescence decay time of F+ centers depends on the s urrounding defects. New data were obtained on the luminescence decay k inetics at 290, 380 and 400 nm. the luminescence being due to exciton- like bodies and complex F aggregate centers.
