The nonradiative changeover rates Keep to the system WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Strength hole. The nonradiative transition fees of Er3+ exhibit temperature dependence per the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is complex https://andywhbvq.idblogmaker.com/32276624/er-yb-yab-crystal-an-overview
