The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://erybyabcrystal30740.kylieblog.com/35366228/considerations-to-know-about-er-yb-yab-crystal
