The nonradiative transition rates Stick to the components WNR = W (0) exp(-alphap), where p is the number of phonons matching the Strength gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation prices is complicated https://robinsong578qke2.therainblog.com/profile
