The nonradiative changeover rates follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power gap. The nonradiative transition costs of Er3+ show temperature dependence in keeping with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure premiums is https://rowanefecy.liberty-blog.com/33292860/5-simple-statements-about-er-yb-yab-crystal-explained
