Lyoluminescence in Ce3+ activated (KNa)Br phosphor for ionizing radiation dosimetry

摘要

The lyoluminescence (LL) in γ-ray irradiated (KNa)Br : Ce3 + phosphors are reported in this paper. LL of (KNa)Br : Ce3 + have been recorded for different γ-ray doses. The nature of variations of LL peak intensities is found to be linear with γ-ray irradiation dose and LL peak intensity is found to be dependent on concentrations (0·1–10 mol%) of added Ce3 + ions in the (KNa)Br host lattice. Negligible fading in the prepared sample is observed.
