In this paper, we show the feasibility of the pulsed-laser ablation technique to grow 20{endash}30-nm-thick, discrete and continuous coatings on particulate material systems so that the properties of the core particles can be suitably modified. Experiments were conducted with a pulsed excimer laser ({lambda}=248&hthinsp;nm, pulse duration=25&hthinsp;ns) to deposit nanoparticle coatings on Al{sub 2}O{sub 3} and SiO{sub 2} core particles by irradiation of Ag and Y{sub 2}O{sub 3}{endash}Eu{sup 3+} sputtering targets. Structural characterization was performed with scanning electron microscopy, wavelength dispersive x-ray mapping, transmission electron microscopy, and scanning transmission electron microscopy with z-contrast. {copyright} {ital 1999 Materials Research Society.}
