A new europium(Ⅲ) complex, EuL3phen, [HL=4, 4,4-trifluoro-1-(4'-o-terphenyl)-1, 3-butanedione, phen= 1, 10-phenanthroline] was synthesized. The complex shows red emission of Eu3+ ions under near ultraviolet (NUV) InGaN chip emission light with a quantum yield of 9%. Red luminescent LEDs were fabricated by assembly of EuL3phen and 395 nm-emitting InGaN chips. When the mass ratio of the complex to the silicone is 1:25, the chromaticity coordinates is x=0.6113, y=0.3125, and the efficiency of the fabricated LED with the europium complex achieves 0.68 lm·W-1.
