The nonradiative changeover premiums follow the method WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Strength hole. The nonradiative transition fees of Er3+ exhibit temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure premiums is challenging https://stewartt481ecz3.activosblog.com/profile
