The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Strength gap. The nonradiative transition rates of Er3+ show temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex https://marioehnop.atualblog.com/39404703/getting-my-er-yb-yab-crystal-to-work
