Non-radiative relaxation rates from 5Fa, 5Sz to 5Fs of Ho3+ \_ m three tellurite glasses were measured as a function of temperature. The expcrlmental behaviour of the nonradiative decay rate IV&") with temperature lies between two theoretical curves fitted to 4 and 5 phonons. Phonon frequencies were
