“…The emission peak positions of the glasses are different in XEL (390-400 nm) and PL (420-440 nm) spectra due to the difference of the luminescent mechanism and excitation energy. 33,42,43 The same phenomenon was observed in the Ce 3+ -doped high silica scintillating glasses reported by Chen et al 42 in 2017.…”

Ce3+‐doped 20Gd2O3–20Al2O3–60SiO2 (GAS:xCe3+) glasses (x = 0.3, 0.7, 1.1, 1.5, 1.9 mol%) with Si3N4 as a reducing agent were prepared. The density of the glasses is around 4.2 g/cm3. With the increase in the Ce3+ concentration, both the photoluminescence (PL) and PL excitation peaks of GAS:xCe3+ glasses show a redshift because the 4f–5d energy levels of Ce3+ ions are narrowed. PL quantum yield and PL decay time of GAS:xCe3+ glasses are 28.32–50.59% and 43–64 ns, respectively. In addition, they both first increases and then decreases with the Ce3+ concentration increasing, reached the maximum when x = 1.1 mol%. The integrated X‐ray excited luminescence (XEL) intensity of the GAS:1.1Ce3+ glass is 23.86% of that of Bi4Ge3O12 (BGO) crystal, and the light yield reaches 1200 ph/MeV with an energy resolution of 22.98% at 662 keV when exposed to γ‐rays. The PL and XEL thermal activation energies of GAS:xCe3+ glasses are independent of Ce3+ ions concentration. Scintillating decay time of the glasses exhibits two components consisting of nanosecond and microsecond levels, and the scintillating decay time gradually decreases with the Ce3+ concentration increasing. The difference between PL and scintillating decay time is discussed regarding the different luminescent mechanisms.

“…This is notably different from the PL emission peak (∼370 nm) due to different luminescent mechanisms when the investigated glasses are excited by various energy regions. 23 X-rays are much more energetic than UV light, which causes a greater Stokes shift, resulting in a red shift of the GABS x glasses during the X-ray excitation process.…”

“…Rare earth ion (RE 3+ ) doped scintillating materials have been extensively studied due to their applications in high‐energy physics, nuclear radiation detection, medicine imaging, and other X‐ray detection fields . Compared to single crystal and ceramic scintillator, RE 3+ (Ce 3+ , Tb 3+ , and Eu 3+ ) doped glass scintillating materials have been widely investigated owing to their low cost, easy preparation, and easy to be made into various shapes . However, the low luminescence efficiency of RE 3+ ‐doped glass scintillators due to the amorphous structure of the glass hinders their practical applications .…”

Tb3+‐doped germanate glass ceramics containing CaF2 nanocrystals were prepared by melt quenching method with subsequent heat treatment. Their microstructures were investigated by XRD and TEM techniques. Their optical properties were studied by the transmittance, the photoluminescence, and the X‐ray excited luminescence (XEL). The luminescence intensity in the glass ceramics under 377 nm light and X‐ray excitations is significantly enhanced. The maximum integrated XEL intensity of the glass ceramics is about 50% of that of the commercial Bi4Ge3O12 (BGO) scintillating crystal. The results indicate that Tb3+‐doped germanate glass ceramic could be a promising scintillating material used in X‐ray detection for slow event.
