The nonradiative changeover rates Stick to the components WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative transition prices of Er3+ exhibit temperature dependence consistent with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation rates is intricate https://dkdp-switch-crystal85174.frewwebs.com/33786864/the-definitive-guide-to-er-yb-yab-crystal
