The nonradiative changeover charges Adhere to the system WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Vitality gap. The nonradiative changeover fees of Er3+ show temperature dependence in keeping with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative peace rates is difficult by the existenc
