Tb³⁺-doped gadolinium aluminium sodium fluorophosphate scintillating glasses were synthesized by the melt-quenching method. The photoluminescence and X-ray induced optical luminescence were investigated with the concentration of Tb₂O₃. For photoluminescence (PL) results, Tb³⁺ ions activated in glasses emit intense green emission peaking at 543 nm by stimulating at 220, 275, and 377 nm. Among three excitations, the wavelength at 275 nm presented the energy transfer mechanism from Gd³⁺ to Tb³⁺ in glasses. The efficient energy transfer was analyzed via faster lifetime with increasing concentrations of Tb₂O₃. According to their PL spectra, the emission intensity is increased up to 5.0 mol%, then, start to decrease with further increasing of Tb³⁺ concentration because of concentration quenching effect. Moreover, the 6.5 mol% of Tb³⁺ in PGNA glasses showed the largest luminescence intensity under X-ray. The integral scintillation efficiency has been studied and exhibited the highest value at 210% when comparing to commercial Bi₄Ge₃O₁₂ scintillation crystal. All results are pointed out the appropriate potential to be X-ray detecting material.

采用熔融淬火法合成了Tb ^{3+掺杂钆铝氟磷酸钠闪烁玻璃。}_{用Tb 2} O ₃的浓度研究了光致发光和X射线诱导的光致发光。对于光致发光 (PL) 结果，在玻璃中激活的 Tb ³⁺离子通过在 220、275 和 377 nm 处激发而在 543 nm 处发出强烈的绿色发射。在三种激发中，275 nm处的波长呈现出玻璃中Gd ³⁺到Tb ^{3+的能量转移机制。}_{随着 Tb 2} O ₃浓度的增加，通过更快的寿命分析了有效的能量转移. 根据它们的PL光谱，发射强度增加到5.0 mol%，然后由于浓度猝灭效应，随着Tb ^{3+浓度的进一步增加，发射强度开始下降。}此外，PGNA玻璃中6.5 mol%的Tb ³⁺在X射线下显示出最大的发光强度。_{与商业Bi 4} Ge ₃ O ₁₂闪烁晶体相比，已经研究了积分闪烁效率并表现出最高值，为210％ 。所有结果都指出了作为 X 射线探测材料的适当潜力。
