The nonradiative changeover premiums Adhere to the components WNR = W (0) exp(-alphap), where p is the number of phonons matching the Power gap. The nonradiative transition costs of Er3+ exhibit temperature dependence in keeping with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest costs is https://martineffda.humor-blog.com/32258890/not-known-details-about-er-yb-yab-crystal
