The nonradiative transition prices Keep 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 consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure prices is intricate https://spencerprrro.p2blogs.com/33673713/top-guidelines-of-er-yb-yab-crystal
