Photodecomposition of Eu3+ complexes with macromolecular ligands based on acrylic acid

Russian Chemical Bulletin Aims and scope

Abstract

The spectroluminescent and photochemical properties of Eu3+ complexes with copolymers of acrylic acid and alkyl methacrylates were studied. It was found that the photochemical behavior of the macromolecular complexes differs significantly from that of the lowmolecular analogs: in the course of photodecomposition the luminescence intensity of Eu3+ noticeably increases rather than diminishes. The efficiency of the luminescence build up of Eu3+ depends on the composition and the structure of the initial macromolecular complexes. A low concentration of the metal, low content of acrylic acid, and increase in the length of the alkyl radical of methacrylate favor the enhancement of the efficiency of luminescence build up of the rare-earth ion.
