The nonradiative changeover fees Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://waldom924jhf5.aboutyoublog.com/profile
