The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://maurices147pol6.wonderkingwiki.com/user
