The nonradiative changeover premiums Keep to the method WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest charges is complicated from the existence of
