Aqueous Method Synthesis and Characterization of SiO2@CsPbBr3 Thin Film Structured Materials

Year: 2025

Type: article

Abstract: Nanocrystalline CsPbBr3 and CsPbBr3 phosphor layers were successfully deposited onto monodisperse, spherical, and non-aggregated SiO2 particles using an aqueous synthesis method. This process led to the formation of SiO2@CsPbBr3 thin-film structured materials. The structural, morphological, and optical properties of the resulting materials were systematically investigated through X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL) spectroscopy, and UV-visible absorption spectroscopy. XRD results confirmed the successful coating of CsPbBr3 layers on the SiO₂ surfaces, this finding further verified by SEM images. The photoluminescence spectra revealed that the SiO2@CsPbBr3 thin film materials exhibited a prominent green emission band, with maximum at 507 nm, indicating their potential in optoelectronic and photonic applications.
