摘要：

TiO2 particles of <10 nm have been prepared by ablating a rutile target rod with a pulsed laser beam, which was assisted by the synchronized injection of an Ar-O-2 mixture. By controlling the wavelength of laser beam, injecting pressure (p) and O-2 concentration in the gas mixture, ultrasmall anatase particles could be obtained. In the present work, lambda = 532 nm, p = 5 x 10(5) Pa and O-2 concentration <5% resulted in anatase particles of <6 nm.
