The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is challenging https://er-yb-yab-crystal28516.blog-kids.com/33305025/a-secret-weapon-for-er-yb-yab-crystal
