The luminescent emission was recorded after photoexcitation at 462 nm. The strong red luminescence at 690 nm corresponds to 4F9/2 → 4I15/2 transition. The luminescence intensity of the prepared phosphor had enhanced 2–4 folds and 4–6 fold after exposing to 150 kGy and 300 kGy gamma radiation, respectively. A linear response between luminescence intensity and irradiation dose was observed through PL dosimetry study. These biocompatible nanophosphors may have promising applications in biomedical and optoelectronic fields.
