Thin films (~100 nm) based on terbium(III) 2-phenyloxybenzoate doped into a polymer matrix were obtained. The terbium content of the mixture was varied from 0 to 11 wt.%. The films were prepared on K8 glass by spin coating from a solution of the mixture in chloroform. The presence of a weak antireflection effect was established from the light transmission spectra of the films on glass. According to the excitation and luminescence spectra, light from the spectral range of 240–330 nm is reemitted in the range of 480–640 nm, where a series of narrow luminescence peaks characteristic of the Tb3+ ion is observed. The effect of the films on the efficiency of three-stage solar cells was studied.
