“…However, the technology is limited by the lack of a stable and efficient red phosphor. A much researched group of novel red phosphor materials are the Eu 3+ doped oxides of Mo and W, including compounds such as Ca(W,Mo)O4:Eu 3+ ,Li + [1,2], M + M 3+ (WO4)2−x(MoO4)x:Eu 3+ (M + = Li, Na, K; M 3+ = La, Gd, Y, Lu, Bi) [3][4][5], M6(W,Mo)O12:Eu 3+ (M = Y, Gd, Lu) [6][7][8][9] and AB(W,Mo)O6:Eu 3+ (A = Ca, Sr, Ba; B = Mg, Ca) [10][11][12][13][14][15][16][17][18]. The first two compounds crystallize in the scheelite structure, where there is enhancement of NUV excitation due to non-centrosymmetric lattice sites.…”

Modified Pechini synthesis routes were developed for synthesis of the novel red phosphor materials NaLa(WO4)(MoO4):Eu 3+ and Ba2CaMoO6:Eu 3+ . Phase pure NaLa(WO4)(MoO4):Eu 3+ was obtained at calcination temperatures ≥ 600 °C using malic acid or tartaric acid as complexing agents. Phase pure Ba2CaMoO6:Eu 3+ was attained using EDTA and citric acid, at calcination temperatures ≥ 800 °C. Choice of complexing agents were discussed on the basis of the solubility of the precursors, metal complex stability constants and conformations of the complexes. The powder properties were characterised using X-ray diffraction, thermal analysis and electron microscopy. Photoluminescence emission intensity was studied as a function of the complexing agents used and calcination temperature of the powders. Maximum emission intensity for NaLa(WO4)(MoO4):Eu 3+ was obtained at a calcination temperature of 600 °C, whereas the maximum for Ba2CaMoO6:Eu 3+ was obtained after calcination at 1100 °C. Both materials displayed desirable optical properties for use as phosphors in white light emitting diodes.
