These glasses do not contain CdSSe or CdS nanocrystals. Luminescence intensity increases and optical transmittance decreases upon laser irradiation. These results indicate that the nanocrystals are formed upon laser irradiation. 关键词: Semiconducting glass;Semiconducting cadmium compounds;Luminescence;Light transmission;Nanostructured materials;Laser beam effects;Light measurement;Cadmium sulfur selenide;Cadmium sulfide
