Scientific schematic diagram of polymeric metal halide thin film, showing polymer matrix in soft-matter style with embedded metal halide units. Highlight metal halides acting as X-ray absorbers. Depict incoming high-energy X-ray photons creating multiple excitons. Show excitons migrating and localizing in different metal halide sites, followed by visible light emission. Style: minimalistic vector illustration, labeled arrows, bright colors for photons, clear scientific diagram suitable for a research figure. Mehr sehen
