The nonradiative changeover rates Keep to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative transition charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees https://erybyabcrystal17273.pages10.com/er-yb-yab-crystal-options-70125707
