Its photoluminescent property was investigated and the optimum concentration of Eu3+ doped in the KGd(MoO4)(2) is 25 mol%. Compared with Y2O2S:0.05Eu(3+), the obtained KGd(MoO4)(2):Eu3+ shows wider excitation band around 400 nm, higher intensity of Eu3+ D-5(0)-F-7(2) emission upon excitation 393 nm, and the CIE chromaticity coordinates (x = 0.655, y = 0.345) are closer to the standard of National Television Standard Committee (NTSC). The optical properties of KGd(MoO4)(2):Eu3+ suggest that it is an efficient red-emitting phosphor for light-emitting diode applications. (C) 2009 Elsevier B.V. All rights reserved.
