The nonradiative transition rates Keep to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is https://erybyabcrystal61626.spintheblog.com/35210335/getting-my-er-yb-yab-crystal-to-work
