Sketch of the experimental set up.
Temporal evolution of light emission (black solid line) and self bias (red line) during the dust formation in an asymmetric capacitively coupled discharge operated in a mixture of acetylene and argon. The blue line (LLS) shows the result of laser light scattering experiment.
Reaction scheme illustrating the formation of nanoparticles in a reactive plasma.
(a) and (b) SEM images of particles collected from different growth stages (morphology and shape comparison).
(a) NEXAFS measurements of particles collected at different growth phases. The grey line represents particles with a diameter of about 10 nm and the black line represents particles with a diameter of about 100 nm. (b) NEXFAS spectra of carbonaceous nanoparticles annealed to two different temperatures: 400 and 800 K.
