Donor‐Acceptor Substituted Carbon Nitride Enables Efficient and Colorful Phosphors

Advanced Optical Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 28, 2025

Abstract Graphitic carbon nitride (g‐CN) is a polymeric semiconductor with low‐cost synthesis, adjustable structure, and excellent stability, which attracts great attention widely used as photocatalyst. On the contrary, it isn't considered promising fluorescent material due to inefficient radiative recombination of electron‐hole pairs. Here, efficient multicolor‐emitting g‐CN phosphors are presented by integrating donor‐acceptor substituents in order replace expensive rare earth‐based phosphors. By incorporating phenyl donor benzonitrile an acceptor, aromatic groups enhance structural rigidity improve photoluminescence (PL) efficiency; meanwhile, extends π ‐conjugated system g‐CN, promotes electron delocalization results tunable PL spectra. As result, substituted materials exhibit blue yellow light emission reach record quantum yield (PLQY) 57%. A white light‐emitting diode fabricated combining modified commercial 450 nm chips, produce bright chromaticity coordinates (0.34, 0.32). The findings provide rational design for high‐performance emitter highlight potential applications optoelectronic devices indoor lighting.
