The nonradiative changeover charges Adhere to the components WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Strength gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace prices is https://erybyabcrystal96283.jaiblogs.com/60126931/er-yb-yab-crystal-an-overview
