The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative transition rates of Er3+ show temperature dependence per the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace rates is sophisticated https://shirinw368vvt0.sunderwiki.com/user
