摘要：

A series of Ba3Lu(PO4)(3): Eu3+ phosphors were synthesized by high-temperature solid-state method, and their UV-vis luminescent properties were investigated. The f-f transitions of Eu3+ in the host lattice were assigned and discussed. The excitation and emission spectra indicate that this phosphor can be excited by near ultraviolet (NUV) light, and exhibits strong red emission. The concentration quenching on Eu3+ emission and its mechanism were investigated. This phosphor shows a good thermal stability at high temperature (similar to 180 degrees C). The fabricated prototype LEDs with Ba3Lu(PO4)(3): Eu3+ and 395 nm-emitting InGaN chips exhibit bright red emission. The present study suggests that Ba3Lu(PO4)(3): Eu3+ can be a potential red phosphor for NUV light-emitting diodes. (C) 2013 Elsevier B.V. All rights reserved.
