Abstract

The Na2O-BaO-B2O3-P2O5 doped with varying concentrations of Gd2O3 and Na2O-Gd2O3-BaO-B2O3-P2O5 glasses were doped with varying concentrations of Eu2O3 (referred to as Eu:NGBaPB) and prepared using the melt-quenching technique. These glasses were analyzed comprehensively in the physical, optical, chemical groups and photo-/radio- luminescence properties. Furthermore, the X-ray imaging was operated to indicate the practical radiation detection of glass. The addition of Eu2O3, the density and refractive index of Eu:NGBaPB glasses increased, while the molar volume decreased. The glass exhibited photon absorption in the UV-NIR regions. Excitation from various sources such as X-ray, ultraviolet, and visible light resulted in a reddish-orange emission at approximately 613 nm, originating from the ⁵D0→⁷F2 radiation state of Eu³⁺. Energy transfer occurred from Gd³⁺ to Eu³⁺ within the glass. These findings highlight the intriguing potential of the glass for applications as an X-ray scintillator.
