The nonradiative changeover charges Keep to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is intricate https://erybyabcrystal29516.bloguetechno.com/a-simple-key-for-er-yb-yab-crystal-unveiled-68306490
