The nonradiative changeover costs Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Vitality gap. The nonradiative changeover premiums of Er3+ show temperature dependence in step with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation rates https://dennise691cbz2.ssnblog.com/profile
