The nonradiative changeover charges Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy hole. The nonradiative changeover prices of Er3+ show temperature dependence in step with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative rest prices is https://erybyabcrystal47801.bloggosite.com/41773899/a-secret-weapon-for-er-yb-yab-crystal
