In this work, we report on sol-gel synthesis of red-emitting [LiY0.88Eu0.12][Mo0.1W0.9O4](2) phosphor and its luminescent properties at room temperature. X-ray diffraction patterns indicate that it presents one main phase with a tetragonal (space group 14(1)/a (88)) structure. Luminescent spectra show that the main emission peaks lies at 613.2 nm and 616.2 nm deriving from D-5(0)-> F-7(2) transition peak splitting due to Mo6+ and W6+ concentration waving in the host. All those exhibit the excellent prospect in light emitting diodes application in the future. (C) 2011 Elsevier B.V. All rights reserved.
