Specific Features of the Induced Absorption Spectra of Fluoroaluminate Glasses Doped with Samarium Ions
Source abstract
Abstract
The induced optical absorption spectra of γ-irradiated fluoroaluminate glasses doped with Eu3+ and Sm3+ ions are investigated. It is shown that Sm3+ ions in fluoroaluminate glasses are protector ions contributing to the suppression of induced absorption in the optical absorption spectra of the studied glasses. It is revealed that the induced optical absorption spectra of the glass samples heat treated at T = 583°C contain two absorption bands with maxima at 300 and 480 nm, which correspond to radiation-reduced (Sm3+)–. The concentration of color centers produced by γ-radiation in fluoroaluminate glasses is estimated. It is demonstrated that prolonged heat treatment of the glass at T = 638 K brings about the decay of (Sm3+)– centers followed by the destruction of the samples.
