Novel multi-component fluoride glasses for light scintillating device applications

Glass scintillators have attracted researchers from all over the world because of their property-driven applications and lower cost when compared to commercial crystals. In this study, multi-component fluoride-based contents doped with cerium fluoride glasses were synthesized and studied to determine their potential for scintillating device applications. The samples were exposed to photoluminescence and a high-energy X-ray/γ-ray beam. The scintillation yield and decay time were measured. Absorption spectra were used to analyze the optical properties, while Raman spectra were used for structural studies. The scintillation yield for 10 mol% CeF₃ content glass was 17.16% compared to BGO crystal, indicating their potential role in scintillating device applications. Fluorine phosphate scintillating glasses for high energy scintillating device applications. • Novel fluorophosphate glasses with high cerium content were synthesized via melt-quenching under argon atmosphere. • Ce 3+ ions show short decay time ranging from 20 to 26 ns. • The scintillating light yield shows 17.16% for 10 mol% CeF 3 content compared with the BGO crystal. • Scintillating analysis revealed a better photo peak and energy resolution was observed with Cs-137 as a source. • Gamma–alpha pulse shape discrimination measured decay rates of 10 mol% CeF₃ glass under gamma and alpha excitation.
