The nonradiative transition costs Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace costs https://lyndona579vur9.wikidank.com/user
