Abstract
Proton irradiation of β-Ga2O3 crystals has been established to lead to a significant increase in the amount of Cr3+ ions being active in luminescence. Using angle-resolved luminescence, the features of the spectra of Cr3+ ions were studied. The high sensitivity of photoluminescence spectra and the related selection rules to the local symmetry of Cr3+ ions in the β-Ga2O3 matrix has been found. The results obtained indicate the potential possibility of using β-Ga2O3 crystals as optical dosimeters of proton irradiation.
