Abstract

Optical emission from the photolytic dissociation of ferrocene Fe(C5H5)2, often abbreviated as FeCp2, in argon atmosphere was studied. The dissociation was performed by using an ArF excimer laser, operating at a wavelength of 193 nm. Two pressure regions were examined. At low (0.1 mbar) pressure, several emission lines of Fe could be identified, however no C, C2, or CH emission lines/bands were found. At a higher (20 mbar) pressure of the FeCp2/Ar gas mixture, a broadband emission identified as blackbody radiation was observed. This blackbody radiation originates from nanoparticles with a mean size of 30 nm, which consist of both metallic iron and amorphous carbon. The initial colour temperature of the particles was 2600 K.
