The nonradiative changeover fees Stick to the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges https://erybyabcrystal05047.blogsumer.com/32345976/the-smart-trick-of-er-yb-yab-crystal-that-nobody-is-discussing
