Notes:
Dispersions of colloidal particles of polycyclic aromatic hydrocarbons were obtained bynanosecond laser ablation. Aqueous suspensions of micron-sized crystals were irradiated with thesecond harmonic output of a Nd:YAG laser and converted into colloidal particles. Ionic and nonionicsurfactants were used in the ablation process to stabilise the particles. Dispersions with goodlong term stability were obtained. A strong dependence of particle formation rate on laser fluencewas found and the particle formation process is discussed on the basis of UV-Vis spectra andmicroscopic examination of the crystals
