The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Power gap. The nonradiative changeover rates of Er3+ show temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative leisure costs is https://dantennlif.humor-blog.com/32175370/the-basic-principles-of-er-yb-yab-crystal
