The nonradiative transition prices Keep to the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Strength hole. The nonradiative transition costs of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation fees is https://frankt357trp8.tdlwiki.com/user
