The nonradiative transition premiums Keep to the formulation WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Strength hole. The nonradiative transition rates of Er3+ exhibit temperature dependence according to the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest costs is complex https://francesh702fda2.blogacep.com/profile
