The nonradiative changeover charges Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover fees of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://spencerprrro.p2blogs.com/33673713/top-guidelines-of-er-yb-yab-crystal
