Abstract
Au nanoparticles were embedded in one-dimensional Eu(III) and Tb(III) hydroxide and oxide nanostructures, and the Au doping effect was understood by contour mapping 2D and 3D-photoluminscecne profiles. Photoluminescence intensity was commonly quenched by dipole-dipole coupling between Au NPs and luminescent centers. The D-5(0)-> F-7(J) emission of Eu(III)) was observed by a direct excitation of Eu(III), while the emission was further quenched upon annealing, and only observed by an indirect excitation. The D-5(4)-> F-7(J) emission of Tb(III) was seen before annealing. Upon annealing, the emission was totally quenched, and a broad emission peak was observed at 550 nm.
