Study on luminescent property of Tb(3+)-doped silicate nano-scintillating glass

By optimizing a Tb(3+)-doped silicate nano-scintillating glass matrix, sensitizer and brightening agent components, the processing conditions such as the melting temperature, holding time, atmosphere, and heat treatment were improved, and the temperature of the heat treatment was changed to generate BaF2 nano-crystal in the glass. The resulting nanocrystals have a better rare earth solubility and a lower phonon energy; therefore the luminescent property of Tb(3+)-doped silicate nano-scintillating glass has been noticeably improved.
