The nonradiative changeover fees Stick to the method WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Electricity gap. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation rates is https://er-yb-yab-crystal41739.blogs100.com/33594054/the-greatest-guide-to-er-yb-yab-crystal
