Journal of Physics: Conference Series Vol. 1145. P. 012029 (1-9)Abstract: Nano-powders of different composition and structure were obtained by nanosecond pulsed laser ablation (Nd:YAG laser, 7 ns, 1064 nm, 20 Hz, 200 mJ) of a metallic copper target in a simple flow reactor at atmospheric pressure. The crystal structure, nanoparticles’ shape, and surface morphology were shown to depend on the gaseous media used (Air, Ar, N2, CO2). CuO nanopowders with a specific surface area 50 m2/g were synthesized by pulsed laser ablation in carbon dioxide and after annealing in air. The optical properties of the obtained powders were also investigated.
