The nonradiative changeover premiums Stick to the system WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated with https://knoxzzatm.blogrenanda.com/39353279/a-secret-weapon-for-er-yb-yab-crystal
