Abstract Nanometer-sized TiO2 sol was prepared by a microwave high-pressure method using terabuty titanate (TBTi) as a precursor, and was contrasted with the one prepared by Ti(SO4)2 hydrolysis method. Fluorescence and resonance scattering spectral properties of TiO2 nanoparticles prepared by the two different precursors were considered. The one using TBTi as precursor exhibits a resonance scattering peak at 320 nm, a synchrotron scattering peak at 470 nm, and three fluorescence emission peaks at 350，400 and 470 nm, respectively. The other one prepared by Ti(SO4)2 has a resonance scattering peak at 340 nm, a synchrotron scattering peak at 470 nm, and two fluorescence emission peaks at 400 and 470 nm, respectively. Influences of the reaction conditions on the resonance scattering intensity are consistent with those on the fluorescence, but the resonance scattering intensity is stronger than the fluorescence intensity.
