Abstract: SrW(1-x)MoxO4 (x = 0, 0.25, 0.5, 0.75, 1) inorganic phosphors were synthesized by the microwave-hydrothermal method (MHM). Structural changes are evaluated by changes in the crystal lattice parameters of SrW(1-x)MoxO4 solid solution. The SrWO4 ? SrMoO4 transition occurs gradually, observing an evolution of the ?2(Ag) (at 918 cm-1) active mode in opposition to the decrease of the ?2(Ag) (at 884 cm-1) mode by the Raman spectra. The color quality of the phosphors and the photometric parameters were estimated using the spectral energy distribution functions of the SrW(1-x)MoxO4 phosphors. The adjustment in chemical composition by the W:Mo molar ratio enabled producing adjustable optical properties. A transition in the emission characteristics of the color (blue ? yellow ? white) was observed. This versatility seen in phosphors is well accepted when it comes to the development of multifunctional materials.
