LUMINESCENCE OF THIN FILMS BASED ON TERBIUM(III) BENZOATE DERIVATIVES

Abstract

The thin films (~100 nm) of complex compounds of terbium(III) with 2-benzoylbenzoic, 2-(4-chlorobenzoyl)-benzoic and 3,4-diethoxybenzoic acids have been obtained. Using the data of electron and optical microscopy, it is found that the complex crystallizes during the film formation. In order to improve the surface quality of the films, the complexes have been doped into a poly-(N-vinylcarbazole) polymer matrix in ratios from 1:1 to 10:1. Based on the dependence of the luminescence integral intensity of the films on the mass ratio of the components, a participation of the polymer in the luminescence excitation of the complexes in the film is supposed.
