Optical properties of the fluoracrilate based fluoropolymers doped with Eu(fod)₃, Eu(fod)₃phen and Eu(tta)₃ by supercritical fluid impregnation are studied. Effects of polymer matrix type on the efficiency supercritical fluid impregnation and optical properties of impregnated polymers are revealed. A comparative analysis of the quantum yield (&lambda_exc = 300 and 380 nm) and thermosensitivity of Eu³⁺ ions photoluminescence depending on the type of ligand and the chemical structure of polymers is performed. The effect of supercritical fluid extraction of photoinitiator residuals from doped fluoropolymer on their optical bleaching at wavelengths below 300 nm is established.
