The nonradiative changeover costs follow the formulation WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in step with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://lorenzh803geb3.glifeblog.com/profile
