Abstract

The Eu³⁺-doped lithium barium gadolinium phosphate glasses were prepared using the conventional melt-quenching method with different concentrations of Eu₂O₃ and Gd₂O₃. The physical characteristics were determined by refractive index, density, molar volume, oxygen packing volume, and oxidation states. Moreover, the optical characteristics were investigated via photoluminescence spectroscopy (PL), UV-vis spectroscopy, Radioluminescence (RL), and decay time. It was found that the Gd₂O₃ concentration of 12 mol% was the optimum composition for further investigations of the Eu₂O₃ doping concentration optimization. The emission spectra of PL and RL showed the strongest intensity of orange-reddish emission (λ_Ex = 394 nm) when the Eu₂O₃ concentration was at 0.3 mol% corresponding to energy transition from ⁵D₀→⁷F_0,1,2,3,4. The oxidation state of Eu³⁺ ions due to the formation of non-bridging oxygens (NBO) in the glass network was confirmed by using X-ray Absorption Near Edge Spectroscopy (XANE). Furthermore, the high transparency and fast decay time in the range of 2.4–2.8 ms displayed the potential to improve laser and radiation detector performances.
