dc.description.abstract	For the first time xBaWO4/(1-x)CaWO4 where (x = 0, 0.25, 0.5, 0.75, 1) nanocomposites powder samples were prepared by co-precipitation method and sintered at 200 degrees C and 400 degrees C. They were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTEM). UV–Visible reflectance, photoluminescence (PL) and PL lifetime studies methods. The intrinsic blue emission of CaWO4 at 420 nm was found to be maximum in xBaWO4/(1-x)CaWO4 nanocomposite sample for the optimized value of 'x' and sintering temperature. The lifetime of this emission was also enhanced for the same sample. The mechanism for the enhanced PL emission intensity and lifetime are also discussed elaborately.	en_US
