The nonradiative changeover premiums Stick to the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Vitality hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest costs https://er-yb-yab-crystal28516.blog-kids.com/33305025/a-secret-weapon-for-er-yb-yab-crystal
