The nonradiative changeover charges Stick to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest premiums is complex
