The nonradiative changeover rates Stick to the system WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in step with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace premiums https://paxtonghgdz.tribunablog.com/er-yb-yab-crystal-an-overview-47523247
