Abstract:   (2564 Views)
In this paper laser ablation of aluminum target in distilled water was used to produce aluminum oxide (alumina) nanoparticles. Nanosecond pulsed laser beam (τ~10ns and λ=1.06µm) with fixed fluence of 46 J/cm2 was used to generate the nanoparticles in this experiment. The effect of ageing of nanoparticles in particle size characteristics was investigated. Scanning electron microscopy (SEM) together with image processing technique was used to evaluate the results. The experimental results showed that size distribution of the nanoparticles can be influenced by ageing due to Ostwald ripening process.
Keywords: colloidal nanoparticles, ageing effect, particle size, pulsed laser ablation
