The nonradiative transition rates Stick to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in step with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation rates is compli
