The nonradiative changeover charges Keep to the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Power gap. The nonradiative changeover prices of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated https://geronimoj839dcb2.hyperionwiki.com/user
