The nonradiative changeover prices Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative relaxation rates is https://hectormcoam.spintheblog.com/35218970/the-best-side-of-er-yb-yab-crystal
