The nonradiative transition charges Adhere to the formula WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the energy hole. The nonradiative changeover costs of Er3+ show temperature dependence according to the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is https://er-yb-yab-crystal63950.bleepblogs.com/33613953/facts-about-er-yb-yab-crystal-revealed
