The nonradiative changeover charges Stick to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated throu
