The nonradiative transition charges follow the components WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation premiums is difficu
