The nonradiative changeover rates Stick to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ show temperature dependence in keeping with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative rest https://troyllkgd.aioblogs.com/86303181/facts-about-er-yb-yab-crystal-revealed
