Photoluminescence stands out among the practical applications of quantum physics in engineering and architecture. After being exposed to solar energy, some substances release photons as a result of the photoelectric effect. These substances were used to create a photoluminescent effect on bicycle paths in research conducted in Europe and Mexico. The research aims to investigate how polymeric residues interact with the luminescent properties of rare-earth materials when making concrete artifacts to illuminate bike and pedestrian paths. The concrete blocks were made with polymeric waste from recycling and luminescent materials, then they were exposed to sunlight and tested for mechanical strength. Experiments revealed that concrete's polymer residue significantly boosts photon emission, particularly when processed via extrusion. Even though the combination of polymers and photoluminescent materials weakens concrete, the research objectives for a product intended to illuminate paths for cyclists and pedestrians were still met.
