Luminescent Performance Study on Dy3+-Doped, Tb3+-Doped and Tb3+/Dy3+ Codoped TeO2-GeO2-BaO Glasses
Dy3+-doped, Tb3+-doped and Tb3+/Dy3+ codoped tellurium-germanium-barium (TeO2-GeO2-BaO) glasses are prepared by high temperature melt-quenching method. The total mole fraction of the network formers of both TeO2 and GeO2 is summed up to 66.6 %. The luminescent performances of TeO2-GeO2-BaO glasses are systematically studied by transmittance and photoluminescence spectra. The optimal doping concentration of Dy3+ and Tb3+ ions in TeO2-GeO2-BaO glasses is determined. And the efficient energy transfer process from Dy3+ to Tb3+ ions are observed clearly. The developed TeO2-GeO2-BaO glass is featured with density of over 5.0 g/cm3, decay time of lower 1 ms, and transmittance of reaching 85% in 400-700 nm wavelength regions, which suggest that the investigated TeO2-GeO2-BaO glass is of significance in scintillation application for detection of high-energy rays.
