The nonradiative transition prices Adhere to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://troyllkgd.aioblogs.com/86303181/facts-about-er-yb-yab-crystal-revealed
