The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Power hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs https://douglasb579ywt0.wikidirective.com/user
