The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ show temperature dependence in keeping with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is challen
