Abstract:
Radiation induced optical absorption processes were studied at room temperature for a set of NaPO3-GdPO4 phosphate glasses doped by Tb3+ ions. Closely similar features were found under X-ray and γ-ray irradiations, while under the intense 308 nm XeCl excimer laser irradiation these effects were further obscured by a possible surface damage. The induced absorption band at 3.3–3.4 eV was ascribed to Tb4+, while bands at 2.3 eV, 2.9 eV and above 4 eV are related to the host matrix-based color centers.
