Abstract

In this work, we reported on high-brightness Eu3+-activated Ca3Lu(AlO)3(BO3)4 (CLAB) red-emitting phosphors. Under 397 nm excitation, the CLAB:Eu3+ phosphors showed intense red emissions at around 621 nm with CIE coordinates of (0.657, 0.343). The optimal doping concentration of Eu3+ ions was found to be 30 mol. %, and the CLAB:0.3Eu3+ sample possessed high-color purity of 93% and ultra-high internal quantum efficiency as great as 98.5%. Importantly, the CLAB:0.3Eu3+ also had good thermal stability. Finally, a white-light-emitting diode (WLED) lamp with good color-rendering index was fabricated by using a 365 nm ultraviolet chip and the phosphor blends of CLAB:0.3Eu3+ red-emitting phosphors, (Ba,Sr)2SiO4:Eu2+ green-emitting phosphors, and BaMgAl10O7:Eu2+ blue-emitting phosphors.
