Absorption spectra of Ho3+ in germanate glasses were measured in the range 300-2500 nm and the intensity parameters were calculated by the Judd-Ofelt theory. Excitation and emission spectra were measured in the visible at a temperature range of 80-573 K. The radiative transition probabilities from the excited states [5F4, 5S2], 5F5, 5I4, 5I5 and 5I6, branching ratios and integrated emission cross-sections were calculated. The non-radiative relaxation rate from the (5F4, 5S2) levels is estimated to be about 2 × 105 s-1.
