Abstract

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 ⁴I_13/2 → ⁴I_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 antimonyphosphate glasses was determined.
