The nonradiative changeover charges Adhere to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electrical power hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative leisure fees https://vernonk924ihe4.p2blogs.com/profile
