The nonradiative changeover fees Stick to the formulation WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Vitality gap. The nonradiative transition fees of Er3+ exhibit temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative leisure fees is https://quentini803gda2.wikipresses.com/user
