Abstract Terbium-lanthanum(or gadolinium)-poly(N-vinylacetamide) complexes were synthesized and characterized by UV-Vis absorption spectroscopy, FTIR, XPS and fluorescence spectroscopy. The results of UV-Vis, FTIR and XPS suggested that terbium and lanthanum(or gadolinium) ions were bonded to amide group of PNVA polymer. Fluorescence experiment indicated that the characteristic emission intensity of terbium ion was greatly increased and possibly sensitized by lanthanum ion(or gadolinium). Moreover, the wavelengths of terbium characteristic emissions were changed slightly.Also the characteristic emission intensity of terbium ion doped with lanthanum ion was better than that with gadolinium ion.
