The nonradiative changeover premiums follow the system WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative rest fees is complicated via https://er-yb-yab-crystal41739.look4blog.com/71513377/the-definitive-guide-to-er-yb-yab-crystal
