| Abstract | In this paper, we report on the series of novel red phosphors (Ba1-xEux)WO4 were synthesized by coprecipitation/calcination method. The morphology and structure were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Photoluminescence (PL) excitation and emission spectra were also used to characterize the (Ba1-xEux)WO4. The results showed that all phosphors present a scheelite-type tetragonal structure with space group (I4(1)/a). The SEM images showed that the grains were like shuttles with sizes ranging from 3.0 to 7.0 mu m. The obtained (Ba1-xEux)WO4 phosphor emitted red emission centered at 612 nm corresponding to the D-5(0) -> F-7(2) transition of Eu3+ when was excited by 394 nm and 465 nm which well matched with near-ultraviolet and blue chips. The optimized concentration of Eu3+ was 20 mol.% for the highest PL emission intensity which was excited at 534 nm. The concentration quenching occurred when the Eu3+ concentration was beyond 20 mol.%. (C) 2012 Elsevier B.V. All rights reserved. |
