The nonradiative changeover costs Adhere to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation rates https://er-yb-yab-crystal16060.blogdiloz.com/33763422/examine-this-report-on-er-yb-yab-crystal
