摘要：

In the article the spectroscopic properties of Yb3+/Er3+ co-doped antimony-phosphate glasses were investigated. The absorption and luminescence spectra were measured and the emission cross-section of Er3+ ions for I-4(13/2) -> I-4(15/2) transition was calculated based on McCumber theory. The resonant energy transfer ( ET) between Yb3+ and Er3+ was obtained under pumping at 976 nm and 940 nm wavelength. In result of dopants optimization the highest efficiency of energy transfer in fabricated glasses was obtained for molar composition 1%Y2O3 : 0.5%Er2O3. The influence of wavelength excitation on value of intensity ratios I-1536nm/I-976nm for antimony-phosphate glasses was determined.
