The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Vitality hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated https://francise691cay2.iyublog.com/profile
