The nonradiative changeover premiums Stick to the components WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity gap. The nonradiative transition costs of Er3+ exhibit temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation prices is challenging https://erybyabcrystal85295.blogsvirals.com/33874301/er-yb-yab-crystal-an-overview
