The nonradiative changeover rates Stick to the components WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Power gap. The nonradiative changeover charges of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure premiums https://holdenhjifb.bloggazzo.com/32298800/5-simple-statements-about-er-yb-yab-crystal-explained
