Abstract

Here, using melamine as the main precursor and 6-(4-(fluoranthen-3-yl)phenyl)-1,3,5-triazine-2,4-diamine as the dopant, a 3-phenylfluoranthene-modified greenish-yellow-emitting g-C₃N₄ derivative was synthesized via thermal polymerization. Excited by blue light chips, high-performance white LEDs were fabricated by using the derivative and red-emitting K₂SiF₆:Mn⁴⁺ as phosphors.
