Undoped and Ce-doped Tb4O7–Al2O3 glasses without glass network-former oxides were synthesized by the containerless method. The X-ray diffraction measurement indicated that the synthesized glass samples were amorphous. In diffuse transmission spectra, the undoped sample showed absorption due to Tb4+, and the reduction of Tb4+ to Tb3+ was observed in Ce-doped samples. In X-ray-induced scintillation spectra, the Ce-doped samples showed luminescence due to the 4f-4f transitions of Tb3+. This result indicated that CeCl3 acted as a reducer and enhanced the luminescence due to Tb3+. In addition, the Ce-doped samples suppressed the thermally stimulated luminescence glow peaks at the low-temperature region.
