Tb 3+ -doped zinc oxide nanocrystals are successfully prepared by hydrolyzing acetate in ethanol.Incorporation of Tb 3+ in ZnO nanocrystals has been proved by XRD,FTIR,PL and PLE measurements.The presence of acetate complexes to zinc atoms on particle surfaces has been testified by FTIR results.Emission from both Tb 3+ ions and surface states in ZnO matrix,as well as their correlation are observed.The cooperation luminescence mechanism suggests that there exists energy transfer between ZnO nanoparticle hosts and the doped Tb 3+ centers.
