The nonradiative changeover charges Stick to the components WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest charges is https://gregoryjrafg.blogunteer.com/33757647/5-simple-statements-about-er-yb-yab-crystal-explained
