Luminescent wollastonite-CePO4 nanocomposites have been successfully synthesized using Ca(NO3)2•4H2O, Na2SiO3•9H2O, and CePO4 by hydrothermal method at 200 oC for 24 h. The precursor nanorods with diameters about 20 nm and lengths several micrometers were obtained by hydrothermal treatment, and after calcination at 600 oC for 3h, the precursor nanorods transformed to wollastonite-CePO4 nanocomposites. Considering the experiment result, a possible growth of the precursor nanorods via the rolling mechanism was also proposed. This is the first report about the synthesis of luminescent wollastonite-CePO4 nanocomposites. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED), energy-dispersive X-ray spectroscopy (EDS), and photoluminescence (PL).
