The nonradiative transition costs Adhere to the components WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Strength gap. The nonradiative changeover charges of Er3+ exhibit temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation rates https://er-yb-yab-crystal51738.ourcodeblog.com/33450599/er-yb-yab-crystal-can-be-fun-for-anyone
