We report the synthesis and characterization of nanocrystalline Pb x Eu y S, a potentially important dilute magnetic semiconductor. The thermolysis of mixed precursors was adapted for the formation of homogeneous alloyed nanocrystals. Energy dispersive spectroscopy provided the atomic composition for Pb x Eu y S nanocrystals, which we juxtaposed with the ratio of the...
Free-standing films of multi-walled carbon nanotubes (MWCNTs), also known as buckypapers, have been fabricated by a two-step process using electrophoretic deposition (EPD). Films of the multi-walled carbon nanotubes were cast onto stainless steel electrodes from aqueous suspensions by EPD. Using a facile mechanical cleavage technique, the films were liberated from their underlying electrodes to yield...
The electrophoretic deposition of cadmium selenide (CdSe) nanocrystal films from a stable hexane suspension onto a dielectric polymer film is reported. The electrodes were prepared by spin casting a ~30 nm thick smooth, defect-free, polystyrene film on silicon substrates. Scanning electron microscopy and atomic force microscopy showed that the CdSe films deposited atop polystyrene possessed morphology...
