The nonradiative transition charges Keep to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy hole. The nonradiative changeover rates of Er3+ show temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest prices is sophisticated with
