Abstract

Abstract : Dy 3+ /Tb 3+ co-doped antimony phosphate glasses (PDTs) were prepared by a common melt-quenching method. The spectra properties of PDTs were analyzed in the range of 300 to 850 nm. The sensitization mechanism of Dy 3+ in enhancing the visible fluorescence of Tb 3+ ions was explored. Since the energy of Dy 3+ ions are effectively transferred to Tb 3+ ions, an enhancement of Tb 3+ emission at 545 nm and a reduction of Dy 3+ emission at 575 nm were observed. The energy transfer (ET) between Dy 3+ and Tb 3+ ions result from the electric dipole interaction. In the PD1T4 sample pumped at 450 nm, a maximum ET efficiency of 63.1% was obtained. The larger values of laser characteristic parameters of Tb 3+ : 5 D4 → 7 F5 transition indicate that these antimony phosphate glasses have great potential for green lasing operation.
