Abstract
Ce3+-doped gadolinium aluminosilicate glass has great potential as a scintillator in neutron detection and high-energy physics. Ce3+-doped gadolinium aluminosilicate glasses with different concentrations of clarifier Sb2O3 were prepared by high temperature feeding method, combined with crucible interlocking technology. Ce4+ ions were reduced to be Ce3+ ions by CO atmosphere in an interlocking crucible. The properties of glass with 0.7 mol% content of Sb2O3 are the best. The glass has a high density (>6.0 g/cm3) and high refractive index (nd > 1.74). Compared with the sample without clarifier Sb2O3, the light yield of the glass increased to about 2 times. From XPS results, it is concluded that the proportion of bridge and non-bridge oxygen in the glass is 58.83 % and 41.67 % respectively. The composition of bridge oxygen in the glass is high, so there are many silicon-oxygen polyhedrons, and the structure in the glass system is stable, which is beneficial to the light yield. It can be seen from the Ce3d spectrum that there is no third characteristic peak of Ce4+ at ∼916 eV, indicating that the content of Ce3+ is more than that of Ce4+. The presence of Ce3+ in the glass is excellent for scintillation properties.
