Trivalent dysprosium ions (Dy3+) doped strontium molybdate (SrMoO4) phosphors were synthesized by solid-state reaction and their photoluminescence (PL) properties were investigated. X-ray powder diffraction (XRD) analysis confirmed the formation of SrMoO4:Dy3+. PL measurements indicated that the phosphor exhibited intense emission at 482, 490 (F-4(9/2) -> H-6(15/2)) and 575 nm (F-4(9/2) -> H-6(13/2)) under UV excitation. The effect of the doping concentration of Dy3+ in SrMoO4:Dy3+ on the PL was investigated in detail. Na+ ion was a good charge compensator for SrMoO4:Dy3+. (C) 2011 Elsevier B.V. All rights reserved.
