The nonradiative transition costs follow the method WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is challenging via https://erybyabcrystal18495.alltdesign.com/5-simple-statements-about-er-yb-yab-crystal-explained-52429590
