The nonradiative transition premiums Keep to the method WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Vitality gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure fees is challenging from
