摘要：

Tm3+ and Ho3+ co-doped TeO2-ZnO-Bi2O3 (TZB) glasses were prepared by the conventional melt-quenching method. Two micrometre emission properties of the TZB glasses exited by 808 nm Laser Diode (LD) were analyzed and discussed. The Judd-Ofelt parameters. spontaneous radiative transition probabilities and radiative lifetime of Ho3+, were calculated based on the absorption spectra by using Judd-Ofelt theory. The absorption spectra and fluorescence spectra were measured. The predicted spontaneous radiative transition rate of I-5(7) -> I-5(8) of Ho3+ is as high as 466.8 s(-1). The result of fluorescence spectra indicates that the maximum emission intensity of Ho3+ 2.0 mu m and of Tm3+ 1.47 mu m emission can be achieved at the concentration of 1 mol% Tm2O3 and 1 mol% Ho2O3 in TZB glasses. The maximum absorption and emission cross-section of Ho3+ near 2.0 mu m are 0.87 x 10(-20) cm(2) at 1951 nm and 1.07 x 10(-20) cm(2) at 2047 nm, respectively. (C) 2009 Elsevier B.V.
