The nonradiative changeover charges Keep to the system WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the Electrical power gap. The nonradiative changeover premiums of Er3+ show temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest rates is https://caideneilml.verybigblog.com/33970050/what-does-er-yb-yab-crystal-mean
