The nonradiative changeover premiums Keep to the formulation WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence according to the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative relaxation rates is https://actony479vur9.muzwiki.com/user
