摘要：

The present work reports the absorption, photoluminescence and decay properties of singly doped Dy3+ and co-doped Dy3+/Tm3+ ions in TeO2+ZnO+K2O+CaO (TZKC) glasses prepared by the melt quenching technique. The glassy nature of the host glass has been confirmed by X-ray diffraction analysis and the primary vibrational modes were determined from the Raman spectrum. Judd-Ofelt (JO) analysis has been used to calculate the radiative transition rates, branching ratios and radiative lifetime of the emitting F-4(9/2) state. The effect of co-doping of different concentrations of Tm3+ ions on the emission properties of Dy3+ ions has been investigated. The decay profiles of the F-4(9/2) level were fitted to double exponential as well as Inokuti-Hirayama (IH) model to determine the energy transfer rates between Dy3+ and Tm3+ ions. The energy transfer rates found to increase with the increase of Tm3+ ions concentration. The chromaticity coordinates and color purity of the emitted light for all glasses were determined.
