PHOTOPHYSICAL PROPERTIES OF POLYETHYLENE AND POLYVINYLCHLORIDE FILMS DOPED BY EU(III) COMPLEXES

Kinetic luminescence spectroscopy was used to investigate the effect o f ligand structure on the rate of photodegradation of compounds of Eu( III) in polyethylene and polyvinylchloride films. It was established t hat complexes of tribenzoylbenzoate of Eu(III) in polyethylene and n-t erephthalate of Eu(III) in polyvinylchloride exhibit the highest photo stability. It was shown that the rate of deterioration of luminescence properties of photoreducing polymer films increases with a rise in th e content of Eu(III) complex. In contrast, addition of stabilizer ethy l-4-bis-cyclohexaamino-oligoethylene-sebacate, slows down deterioratio n of luminescence.
