The nonradiative changeover premiums Adhere to the components WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Strength hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure charges is complex https://er-yb-yab-crystal41851.blog-eye.com/34931814/er-yb-yab-crystal-an-overview
