The nonradiative changeover rates Adhere to the system WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ show temperature dependence according to the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex with
