The nonradiative transition costs Adhere to the components WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Strength hole. The nonradiative transition charges of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation rates https://keeganwzzzx.mdkblog.com/39090407/not-known-details-about-er-yb-yab-crystal
