The nonradiative changeover costs Keep to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity gap. The nonradiative transition fees of Er3+ show temperature dependence in keeping with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult be
