Preparation of Perovskite-Embedded Co-polymer Particles and Their Application for Photonic Crystal-Based Optical Films |
| 초록 |
Co-polymer particles (CPs) containing organic-inorganic hybrid perovskite nanoparticles (OIP NPs) are prepared via self-emulsion polymerization (SEP) and vapor-assisted solution process (VASP). The diameter of the CPs is precisely controlled through the concentration and ratio of the monomers, and shows narrow size distributions (PDI ＜ 0.03). The prepared OIP precursor-embedded CPs are self-assembled to 3D photonic crystals (PCs), then the embedded precursors are converted to OIP through VASP. The OIP-embedded 3D PCs are applied to a down-conversion OIP LEDs as an emissive and light extraction layer. OIPs embedded in the 3D PC show improved optical properties than the bare OIPs due to the interaction between the PL spectrum of OIPs and the photonic bandgap of the 3D PCs. The PL intensity of OIPs are enhanced ~12 % with reduced full width at half maximum (FWHM). In addition, OIP embedded in 3D PCs show improved viewing-angle and environmental stability over the bare OIPs. |
