Synthesis of nanotructured metal-carbon materials by laser irradiation is an actual branch of laser physics and
nanotechnology. Laser sources with different pulse duration allow changing the heating rate with realization of different
transition scenarios and synthesis materials with various physical properties.
We study the process of the formation of nanostructured metal-clusters and complexes using laser irradiation of
colloidal systems which were consisted of carbon micro- nanoparticles and nanoparticles of noble metals.
For carbon nanoparticles synthesis we use the method of laser ablation in liquid. For the realization of different
regimes of laser surface modification of the target (glassycarbon and shungite) and the formation of micro- nanoparticles
in a liquid the YAG:Nd laser with a pulse duration from 0.5 ms up to 20 ms (pulse energy up to 50J) was applied.
We have used the CW-laser with moderate intensity in liquid (water or ethanol) for nanoparticle of noble metals
synthesis. Thus, colloidal systems were obtained by using CW-laser with λ = 1.06 μm, I ~ 105-6 W/cm2, and t = 10 min.
The average size of resulting particles was approximately about 10 to 100 nm. The nanoparticle obtaining was provided
in the colloidal solution with different laser parameters.
In this work we have investigated the mechanism of the metal-carbon cluster formation during the process of
irradiation of colloidal system which were consisted of separate carbon, silver and gold nanoparticles. This system was
irradiated by nanosecond laser (100 ns) with average power up to 50W.
