The nonradiative changeover premiums Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative transition prices of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees is intricate because of the
