Abstract

Tb-activated fluoride oxide tellurite glasses were synthesized by high-temperature melting method. The effects on the density, transmission, lifetimes and luminescence properties under UV and X-ray were investigated and the energy transfer mechanisms between Gd3+ and Tb3+ analyzed and discussed. These glass scintillators have a unique combination of properties including high scintillating light output, high density. The results also show that, with increasing concentrations of Tb3+ and Gd3+, a monotonic increase in the energy transfer efficiencies from Gd3+ to Tb3+ is observed followed by enhance emission centered under UV and X-ray excitation..
