The nonradiative changeover premiums Adhere to the formulation WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ exhibit temperature dependence per the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace costs is https://charliennlid.blogaritma.com/31517201/er-yb-yab-crystal-an-overview
