The nonradiative changeover charges Keep to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality gap. The nonradiative changeover charges of Er3+ exhibit temperature dependence consistent with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative leisure premiums is https://campbelll924jig4.dailyblogzz.com/profile
