We synthesized Mn+4 doped SrLaMgNbO6 phosphors by a solvothermal method. The influence of Mn4+ concentration on emission of SrLaMgNbO6:Mn4+ phosphor was investigated. The synthesized phosphors have a single phase and flower-like microstructure. Under the excitation at 321 nm, SrLaMgNbO6:Mn4+ phosphors show intense red emission with three peaks, which come from the E-2(g), T-2(2g )-> (4)A(2g) transitions of the 3d(3) electrons in the octahedral MnO68 complex.SrLaMgNbO6:Mn4(+) phosphors have potential applications in WLEDs. The addition of SrLaMgNbO6:Mn(4+ )phosphor can decrease the CCT value and increase R-a value of white lights emitted by WLEDs. (C) 2018 Elsevier B.V. All rights reserved.
