The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative changeover fees of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure costs is https://er-yb-yab-crystal43072.techionblog.com/33140346/getting-my-er-yb-yab-crystal-to-work
