The nonradiative transition charges Stick to the system WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Strength hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative rest fees is https://erybyabcrystal95173.affiliatblogger.com/85348251/a-review-of-er-yb-yab-crystal
