Abstract
This paper reports the synthesis of TiO2 spherical nanoparticles by laser ablation in liquid (LAL), using sintered TiO2 as a target and water as a liquid medium. The resultant TiO2 nanoparticles were identified to be the rutile phase by the XRD and UV-vis absorption measurements. The laser wavelength and pulse energy did not alter the spherical shape but affect the particle size of the TiO2 nanoparticles. The pH adjustment led to the formation of the well-dispersed nanoparticles but had little effect on the particle size. This study suggests that LAL is a powerful way to make spherical nanoparticles.
