New photoluminescent coatings were developed for safety applications using an acrylic emulsion combined with cellulose nanofibers (CNF; 15-28 nm) and rare-earth doped strontium aluminate (RSA) nanoparticles (8-22 nm). The impact of the RSA content on the coating formulation features was examined. CNF serves as a compelling reinforcing material for coatings due to its unique characteristics, including biodegradability, renewability, and biocompatibility. The prepared coatings were applied to tinplate panels. RSA was synthesized in its nanosized form, as characterized by transmission electron microscopy (TEM), to enhance its distribution and functional properties within the coating formulation. The prepared coatings were analyzed using X-ray fluorescence (XRF), energy-dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR). The transparency and coloring properties of the coating films were analyzed using photoluminescence spectra and three-dimensional coloration measurements. An emission peak was detected at 517 nm upon excitation at 365 nm. The scratch resistance, superhydrophobic properties, and corrosion resistance were examined. CNF was identified as a crucial element in the anti-corrosion efficacy. The provided acrylic emulsion paints exhibited favorable outcomes when combined with cellulose nanofibers and sodium hexametaphosphate. The most prolonged luminescence emission was monitored for almost 60 min in darkness for the RSA content of 12 % (w/w).
