Inorganic perovskite quantum dots (PQDs), specifically CsPbX3 (X = Cl, Br, or I), have attracted considerable interest for their exceptional optoelectronic properties. However, development is constrained by instability arising from particle mobility. The tendency of small-sized PQDs to aggregate into larger green-emitting presents a significant challenge the widespread application blue-emitting CsPbBr3 PQDs, particularly in scenarios demanding pure blue light emission. To tackle this challenge, we utilized straightforward yet efficient synthesis approach immobilize and encapsulate onto APTES-capped silica microspheres. In contrast CsPbBr3-A-SiO2 composites display outstanding stability under UV exposure, heat, aqueous conditions, consistently maintaining single emission peak photoluminescence spectrum, accompanied an extended fluorescence lifetime. Transmission electron microscope analysis revealed transformation dispersed aggregated nanostructures nanorods with time, while encapsulated maintained uniform dispersion. By encapsulating on 310 nm chip, stable light-emitting diodes color coordinates approximately at (0.148, 0.05) can be fabricated. synergistic unstable effectively enhance anticounterfeiting measures, information encryption, digital technologies. Integrating materials anticipated show promise security, various other domains.
