Photolysis of light-transforming polymeric materials based on europium(III) nitrate with 1,10-phenanthroline and quinaldic acid

Abstract

Light-transforming polymeric materials based on two luminophor dopants (europium(III) nitrate with 1,10-phenanthroline and quinaldic acid characterized by intense luminescence in the spectral range of 400–650 nm) have been fabricated. It has been established that the photoresistance of polymeric materials based on the fabricated composites is higher than that of the polymeric material activated with europium(III) nitrate with 1,10-phenanthroline. It has been also established that luminescence and photochemical characteristics of polymeric composites are determined by the dopant molar ratio: the maximum luminescence intensity and photoresistance characterize the polymeric material containing europium(III) nitrate with 1,10-phenathroline and quinaldic acid at a molar ratio of 1: 2.
