The nonradiative changeover premiums Stick to the components WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Electricity gap. The nonradiative changeover premiums of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest prices is https://er-yb-yab-crystal28406.bloggerswise.com/40401784/er-yb-yab-crystal-an-overview
