The nonradiative changeover charges follow the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://judahgigda.blog-kids.com/33476552/5-simple-statements-about-er-yb-yab-crystal-explained
