A series of fatty acids complexes were synthesized from rare earth elements Europium(Eu) and Terbium(Tb) with the ligands of different Fatty acids(CH_3COOH, C_3H_7COOH,C_5H_(11)COOH,C_7H_(15)COOH,C_(11)H_(23)COOH,C_(17)H_(35)COOH) via Crystalliza -tion method and Saponification method in this paper.New kinds of fluorescent acryl amide polymers were manufactured by aquous polymerization using NH_4[RE(F)_4·H_2O] (RE=Eu,Tb;F=C_2,C_4) complexes and acryl amide monomer.We also fabricated three photolumin...
