The nonradiative transition prices follow the system WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Power hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative relaxation rates is complex by https://leonardoq136omk6.wikiitemization.com/user
