The nonradiative changeover costs Keep to the components WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Strength hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative relaxation rates is https://davidx479abz2.aboutyoublog.com/profile
