N2 - Octahedron-like KLa(MoO4)2 microcrystals with monoclinic scheelite-type structure were successfully synthesized by a low cost molten salt method using KCl as flux. The as-prepared products were characterized by powder X-ray diffractometer (XRD), scanning electron microscope (SEM) and photoluminescence spectrometer (PL). The results indicate that calcining temperature and reaction time have great impacts on the morphologies and sizes of the product. The emission spectra recorded for an excitation wavelength at 289 nm exhibit a strong emission peak at 616 nm, corresponding to the 5D0→7F2 transition of Eu3+. The quenching concentration was found at 15 mol% doping of Eu3+. The commission international Del’Eclairage (CIE) chromaticity coordinates of the phosphors were about (0.6632, 0.3365) and it is very close to the standard red chromaticity of NTSC. Therefore, the phosphors could be promising for white light-emitting diodes.
