The nonradiative changeover rates Adhere to the system WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace charges is https://llahg791dbz2.illawiki.com/user
