The nonradiative changeover 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+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://er-yb-yab-crystal42962.blogpixi.com/33397267/5-simple-techniques-for-er-yb-yab-crystal
