The Influence of High Temperature on X-Ray Luminescence Performance of BGO and BaF2 Scintillation Crystals
Year: 2026
Type: conference-paper
Abstract: This study examines the luminescence performance of two single-crystal scintillators under X-ray excitation, as a function of temperature. Two identical cubic samples of bismuth germanate (Bi4Ge3O12-BGO) and barium fluoride (BaF2) crystals are irradiated by a medical-type X-ray source, and their luminescence output is collected and measured while they are heated from room temperature up to 174 °C. The luminescence efficiencies of BGO and BaF2 scintillators decreased by 87.5% and 79.48%, respectively, with increasing temperature. BGO showed higher luminescence efficiency results in most of the examined temperature range; however, BaF2 minimized the differences at temperatures approaching 174 °C. The combination of economic accessibility and thermal performance at higher temperatures renders BaF2 a good choice for harsh environments and large-scale applications where budget and durability are as critical as performance.
