Abstract

This study investigates the influence of gamma irradiation (up to 10⁸ rad) and subsequent thermal annealing (700 °C, up to 9 h) on the spectral characteristics of Y₂SiO₅:Er3⁺ crystals. It has been established that these treatments induce the formation of oxygen vacancies in the crystal, leading to coordination transformations from Er1 to Er2 sites. This is accompanied by a redistribution of the intensities of f–f transitions, which enabled the spectroscopic identification and differentiation of two types of Er3⁺ centers with distinct coordination environments. Induced absorption and luminescence bands associated with the formation of F and F⁺ centers were observed. It was demonstrated that changes in the local crystal field surrounding the Er3⁺ ions lead to noticeable Stark splitting, as evident in both absorption and photoluminescence spectra. The results demonstrate the potential for controlled modification of the material’s optical properties via coordination rearrangement, which is of interest for photonic and quantum technologies.
