Abstract

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.
