摘要：

A strong 694 nm Ruby laser beam was used to ablate films of gold, nickel and carbon in a solvent (water, 2-propanol, cyclohexane). Colloidal solutions of these materials were obtained. The mean size of the colloidal gold particles depends on the laser intensity. Small graphite particles (several microns) suspended in toluene were also exposed to the laser flash. Ablation of these particles in the plasma generated by the laser leads to an orange solution which contains carbon-60, carbon-70 and other carbon clusters which have not yet been identified.
