摘要：

The paper considers the generation of colloidal gold nanoparticles by laser ablation of thin gold films of variable thickness in deionized water. The effect of laser fluence, pulsewidth, exposure, and film thickness on the generation of nanoparticles, its productivity and ergonomicity, particle dispersion and size is studied along with the related ablative mass loss from the films.
