研究了Lumilass-B荧光玻璃的光学、闪烁和剂量学性能。该玻璃显示出紫外吸收带，这可归因于玻璃基体中Eu2+离子从4f7（8S7/2）基态向4f65d激发态的转变。当x射线激发玻璃时，在PL光谱中出现400 nm的放射发光带。这被确定为Eu2+从5d激发态到4f7（8S7/2）基态的过渡。计算出脉冲x射线激发下的闪烁衰减时间约为630 ns。在所研究的剂量范围内，热释光（TL）和光激发发光（OSL）强度分别在0.25 ~ 200mgy和光激发发光（OSL）强度呈线性关系。
The optical, scintillation, and dosimetric properties of Lumilass-B fluorescent glass were studied. The glass showed an ultraviolet absorption band that can be attributed to the transition from 4f7(8S7/2) ground state to the 4f65d excited state of Eu2+ ions in the glass matrix. When an X-ray excited the glass, the radioluminescence band appeared at 400 nm as in the PL spectrum. This is identified as the transition from the 5d excited state to the 4f7(8S7/2) ground state of Eu2+. The scintillation decay time under excitation with the pulsed X-ray was calculated to be about 630 ns. The irradiation dose response of the thermoluminescence (TL) and optically-stimulated luminescence (OSL) intensities was linear in the studied dose range at 0.25–200 mGy and 0.25–16 Gy, respectively.
