The study focuses on the synthesis and characterization of photofunctional Eu3+/Tb3+ hybrid materials, which are inorganic silica covalently linked to organic polymer chains through sulfide bridges. The main chemicals used include 2-thiosalicylic acid (TSA), crosslinking reagents 3-chloropropyltrimethoxysilane (CTPMS) and 3-(triethoxysilyl)-propyl isocyanate (TESPIC), tetraethoxysilane (TEOS), europium and terbium nitrates, and organic polymers polyacrylamide (PAM) and polyethylene glycol (PEG). These chemicals serve to create sulfide-bridged molecular linkages and polymeric silane derivatives, which are then assembled into multi-component hybrid materials through co-hydrolysis and co-polycondensation with TEOS. The purpose of these materials is to improve photoluminescence properties by integrating the benefits of both inorganic silica and organic polymers, such as enhanced thermal or optical stabilities, chemical stability, and mechanical strength. The study aims to develop hybrid systems with improved luminescence behavior for potential applications in luminescence and laser fields.
