In this paper the fluorescence quantum efficiencies and branch ratios of ytterbium doped oxide glasses are firstly calculated with equation derived from the reciprocity principle. It is shown that using absorption spectra of ytterbium doped glasses including borate, phosphate, niobosilicate, telluorogermanate and tellurite glasses, the fluorescence quantum efficiencies are obtained and varies from 80% to 99%, increasing with decreasing phonon energy of glass hosts. The branch ratios change slightly as glass hosts with different phonon energy and are about 40%, 30%, 30%, 0% around 970 nm, 1000 nm, 1020 nm, 1050 nm wavelength, respectively.
