The nonradiative transition rates Keep to the formulation WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Strength hole. The nonradiative transition charges of Er3+ exhibit temperature dependence consistent with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://shirinw368vvt0.sunderwiki.com/user
