The nonradiative changeover costs Stick to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest prices is sophisticated from th
