| Abstract: | The fluorescent and photochemical properties of Eu (III) with copolymers of acrylic acid and butyl methacrylate were investigated. It was found that photochemical behavior of Eu3+ complexes with copolymers is essentially different from those of Eu3 with polyacrylic acid - in the former Eu3 luminescence intensity during photolysis noticeably enhances rather than reduces. It has been found that the presence of steric hindrances and coordinatively unsaturated structures in the initial complexes with copolymer and peculiarities of the photodecomposition of macromolecular ligand favors the enhancement of the luminescence during the photolysis |
