•The novel LaBMoO6:Eu3+ red-emitting phosphor was synthesized.•The PLE spectra revealed that when x ⩽ 0.05, all the charge-transfer states centered at 350 nm.•LaBMoO6:Eu3+ phosphors emitted bright red light under 350 nm excitation.
A novel high-efficiency near-UV light-emitting diode (LED)-based color-conversion phosphor, red-emitting LaBMoO6:Eu3+, was synthesized by solid-state reaction for the first time, and its photoluminescence (PL) properties were investigated for application in white-light-emitting diodes (W-LEDs). The as-synthesized phosphors were characterized by X-ray powder diffraction, photoluminescence excitation (PLE), and PL emission spectra. The PLE and PL emission spectra revealed that when x ⩽ 0.05, all the charge-transfer states centered at 350 nm, and LaBMoO6:Eu3+ phosphor emitted bright red light under 350 nm excitation. The CIE (Commission Internationale de l’Eclairage) chromaticity coordinates for LaBMoO6:Eu3+ red phosphor were simulated and located in the red region. All the results indicate that the developed LaBMoO6:Eu3+ phosphor could be potentially used as W-LEDs.
