Poly-N-vinyl acetamide (PNVA) was synthesized by free radical polymerization.Then a series of complexes of Eu3+ with poly-N-vinyl acetamide were prepared by adding different amount of EuCl3 into the polymer.They were characterized by using UV-visual
IR and fluorescence spectroscopies.The results indicate that Eu3+ ion is incorporated with oxygen atoms of carbonyl in PNVA by electrostatic force.The fluorescence emission intensity was measured on solution samples.The coordination compound can emit red fluorescence at 613 nm after being excited by 277 nm ultraviolet rays
and the fluorescence strength reaches a maximum at an Eu3+ content around 0.226 wt%.
