Abstract

The complexes of rare earth ion (Tb

) with acetic acid and ammonium acetate ligand have been synthesized. The transparent photoluminescent polyacrylamide materials were prepared by aqueous polymerization with acrylamide monomer. Their fluorescent properties were studied. Both complex and polymer display strong characteristic emission of Tb

ion or Eu

ion. The decay curves of Tb

ions

emission show that there are two fluorescent lifetimes of Tb

ion

emission in both complex and polymer. The polymer has longer apparent fluorescent lifetime but lower quantum efficiency than corresponding complex.
