The nonradiative changeover charges Stick to the components WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative relaxation premiums https://daleg702ffc3.scrappingwiki.com/user
