摘要：

Thin films (similar to 100 nm) of mixed-ligand complexes of terbium(III) with 3,5-diethoxybenzoic, 2,5-dimethoxybenzoic, and 3,4-diethoxybenzoic acids and phenanthroline and the Tb complex with only 3,4-diethoxybenzoic acid have been obtained. Electron and optical microscopy found that the complex crystallized during formation of the films. The complexes were doped into a poly-N-vinylcarbazole matrix in weight ratios from 1:1 to 10:1 to improve the quality of the film surface. It was assumed that the polymer participated in excitation of luminescence of the complexes in the film based on the dependence of the integral intensity of the film luminescence on the weight ratio of components in it and on the kinetics of film luminescence.
