- Iran-containing nanoparticles were made by laser-assisted (ArF excimer laser, lambda = 193 nm) photolytic dissociation of ferrocene (Fe(C5H5)(2) or FeCp2) in argon and an oxygen/argon gas mixture. The particle-size distributions were obtained on-line by u

- 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.

- Palladium nanoparticles were deposited using a sequential electroless deposition technique on the pore walla of nanoporous anodic alumina. For the particle deposition a Pd(NH3)42+ solution was soaked in the alumina membrane and a heated air flow was applied in order to reduce the palladiumcomplex to palladium metal nanoparticles. By repeating the deposition process the size of the nanoparticles could be tailored in this investgation between 6 and 11 nm. The size of the nanoparticles was also affected by the concentration of the Pd(NH3)42+ solution i.e., highconcentration yielded larger particles mean diameters. The samples were investigated using high resolution scanning electron microscopy, x-ray diffraction (XRD), inductively coupled plasma with a mass spectometer, high resolution transmission electron microscopy , and energy dispersive spectroscopy (EDS). Analysis revealed narrow size distributions of the particles as well as uniform particle coverage of the pore walls. No by-products were observed with EDS, and with the XRD analysis the metallic palladium crystallinity was confirmed.
