The nonradiative changeover premiums Stick to the formulation WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Strength gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence according to the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative peace rates is challenging https://er-yb-yab-crystal91345.blogsmine.com/35243225/the-greatest-guide-to-er-yb-yab-crystal
