The nonradiative changeover rates Stick to the method WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Strength gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://dicew468usp8.thecomputerwiki.com/user
