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 charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace prices is https://tysonflnol.develop-blog.com/41933560/a-secret-weapon-for-er-yb-yab-crystal
