摘要：An alternative low cost method was proposed for the low temperature (600 C) preparation of CdTiO3 nanoplates, using low-melting-point Cd(NO3)(2 center dot)4H(2)O and high-reactive-activity TiO2 nanocrystals as the reactants. The structure, composition, specific surface area, thermal stability and optical properties of the as-synthesized products were characterized by X-ray diffraction, energy dispersive X-ray spectroscopy, field emission scanning electron microscopy, Brunauer-Emmett-Teller surface area analysis, UV-vis absorption and room temperature photoluminescence spectra. The as-synthesized CdTiO3 nanoplates were thermally stable at temperatures <= 900 degrees C. and their phase changed from ilmenite to perovskite when heated in air at 1000 degrees C for 2 h. Besides, they exhibited a strong and broad visible light emission in the range of about 470-750 nm upon laser excitation at 325 nm, enabling their use as a luminescent material.
