Luminescent and photochemical properties of light-transforming materials

Resumo

Composite light-transformig polymer materials were prepared from europium(III) and ittrium(III) cinnamates and high-pressure polyethylene. It was shown that combined use of these rare earth complexes leads to intense luminescence in the 400–700 nm region. Luminescent and photochemical characteristics of these polymer composites were determined by the dopant molar ratio: samples containing polymer europium cinnamate and ittrium cinnamate at a molar ratio of 1: 0.5 had the maximum luminescence intensity and photostability.
