A novel broadband emission phosphor Ba3LiMgV3O12: Eu3+ is synthesized by a solid-state reaction method. The X-ray diffraction analysis indicate that Ba3LiMgV3O12 single phase obtained at 800 degrees C show the same crystal structure with Ba3V2O8. The excitation and emission spectra exhibit that the excitation band distributes between 260 nm and 395 nm and peaks at 343 nm, emission band covers from 400 nm to 600 nm and centers at 500 nm, respectively. The emission band peaks at 613 nm originated from charge transfer transitions from Ba3LiMgV3O12 host to doped Eu3+ ions can be observed when the Eu3+ ions doped into the host. White light can be obtained with coordinate of (0.312, 0.321) from the fabricated light emitting diodes (LEDs) with the doped content of Eu3+ ions at 5.0 mol%, which shows that the phosphor is a promising single-phase phosphor for near ultraviolet (NUV) LEDs.
