Abstract

Oxide nanoparticles were synthesized using an advanced pulsed laser ablation system capable of reproducibly generating nanoparticles with a narrow size distribution. The production rate, size distribution, morphology, and structure of the oxide nanoparticles were investigated. Crystalline titanium, aluminum, tin, indium, nickel, zinc, and iron oxide nanoparticles were produced in an oxygen atmosphere (200 mbar) using a Nd:YAG laser (wavelength 355 nm, energy/pulse 60 mJ, repetition rate 10 pps, pulse duration 5 ns, energy density 5 J/cm2). The particles were produced at an energy-related rate of 0.55- 8.94 mg/J. Sizes varied between 2 and 24 nm with mean sizes in the range 3.2-10.8 nm. All oxide nanoparticles had a lognormal size distribution..
