State-of-the-art luminescent materials based on wood veneer with superior strength, transparency, and water resistance

• Veneer is demonstrated for light emission and nanomanufacturing. Fluorescent wood obtained by delignification, Hantzsch reaction densification. The veneer shown high strength, tunable hydrophobicity biodegradability. prospects of optical windows encrypted films are demonstrated. Current energy luminescent materials utilize polymers to encapsulate fluorescent carbon nanodots dyes but they usually lack stability Here, we introduce an alternative nanotechnology produce (veneer) with UV resistance tailorable surface energy. First, transparent (FTW) as a support aggregation-induced (AIE) in-situ acetoacetate delignified (AA-DW). Highly aligned cellulose nanofibers present in AA-DW facilitate FTW densification, ensuing exceptional mechanical performance (tensile strength Young's modulus up 422 MPa 45 GPa, respectively). Simultaneously, the conjugated structures display transparency (83%), haze (80%) anisotropy. new system be biodegradable effective (fluorescent) well films.
