The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Strength gap. The nonradiative transition charges of Er3+ show temperature dependence according to the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is challenging https://dominickfhfcz.bloguerosa.com/32158550/a-simple-key-for-er-yb-yab-crystal-unveiled
