Fluorescent materials have garnered significant interest in optical display and information storage fields for their vibrant and distinct color presentation. Extensive research has been conducted on carbon-based fluorescent materials owing to their environmental sustainability, versatility, and adjustable optical properties. However, it is difficult to integrate high-resolution fluorescent structure on various wafer-level substrate for abundant optical display and information storage. This study successfully fabricated wafer-level carbon-based fluorescent flexible film with ∼100 μm thick using a standardized “lithography + annealing” process. The sample demonstrates high fluorescence intensity with a peak at 603 nm and fluorescence lifetime of 0.3517 ns. When excited by light of 365 nm, 485 nm, and 525 nm wavelengths, the film displays yellow, green, and red, showcasing exceptional color tuning capability. This flexible film is portable and can be readily integrated with various substrates, offering significant technical and theoretical support for advancing carbon-based optical display and information storage technologies. |
