The nonradiative changeover rates follow the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest rates is https://ashleyv368utq8.wikiworldstock.com/user
