總結:	Title screen The possibility of creating luminescent films based on highly porous polymer materials doped with the europium complex Eu(dbm)3 · H2O in a supercritical carbon dioxide medium using ethanol as a co-solvent is demonstrated. The initial polymer samples are polytetrafluoroethylene films obtained using thermal spraying or electrospinning techniques and polybenzimidazole films with foam-like structures obtained using laser irradiation. Deposition of the Eu complex in the pores of such materials (up to a few micrometers in size) leads to the appearance of bright characteristic photoluminescence (PL) in the red region, the intensity of which depends on the impregnation method and subsequent processing of the samples. An analysis of the intensity ratio between the electric dipole and magnetic dipole components of the PL spectra allow us to draw conclusions about the changes in the nearest environment of Eu3+ ions in each of the studied host materials.
