The nonradiative transition fees Stick to the components WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative rest fees is https://erybyabcrystal85162.techionblog.com/33202733/er-yb-yab-crystal-an-overview
