The nonradiative transition charges Stick to the components WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative relaxation premiums is https://manuelkmqab.imblogs.net/84436575/er-yb-yab-crystal-an-overview
