Abstract

Non-radiative relaxation rates from ⁵F₄, ⁵S₂ to ⁵F₅ of Ho³⁺ in three tellurite glasses were measured as a function of temperature. The experimental behaviour of the nonradiative decay rate W_nr(T) with the temperature lies between two theoretical curves fitted to 4 and 5 phonons. Phonon frequencies were obtained from Raman measurements, a correlation was found between the magnitude of W_nr(0) and the amount of disorder in glass.
