The nonradiative transition fees Adhere to the system WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electricity hole. The nonradiative transition fees of Er3+ show temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure rates is difficult https://brookseciji.blogcudinti.com/34926159/the-2-minute-rule-for-er-yb-yab-crystal
