:Ce nano-crystals were synthesized using the co-precipitation technique. Nano-crystals were characterized for their crystal structure, particle size, organic coating and photoluminescence behavior using X-ray diffraction, SEM, FTIR and Photoluminescence spectroscopy. The crystallite size was calculated from the XRD pattern. The surface modified nano-crystal composite exhibits emissions at 306, 372 and 445 nm.
