The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest rates is complex throu
