摘要：

In this study, the red phosphors, Y2W1-xMoxO6:Eu3+ and Y2WO6:Eu3+,Bi3+, have been investigated for light-emitting diode (LED) applications. In Y2WO6:Eu3+, the excitation band edge shifts to longer wavelength with the incorporation of Mo6+ or Bi3+ ions. The emission spectra exhibit D-5(0) -> F-7(1) and D-5(0) -> F-7(2) transition of Eu3+ ion at 588, 593, and 610 nm, respectively. Moreover, the bluish-green luminescence of the WO66- at about 460 run is observed to decrease with the incorporation of Mo6+, which results in pure red color. Thus, this Study shows that the red phosphor, Y2WO6:Eu3+, incorporated with Mo6+ or Bi3+ ions is advantageous for LEDs applications. (C) 2009 Elsevier B.V. All rights reserved.
