The nonradiative changeover fees Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in line with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace premiums is difficult via th
