The ability to incorporate a dopant element into silicon nanocrystals (NC) and quantum dots (QD) is one of the key technical challenges for the use of these materials in a number of optoelectronic applications. Unlike doping of traditional bulk semic

Laser ablation of either Ni or Fe is used to create nanoparticles within a reactive flame environment for catalysis of carbon nanotubes (CNTs). Ablation of Fe in a CO-enriched flame produces single-walled nanotubes, whereas, ablation of Ni in an acet

Initial results are presented here for laser-induced restructuring of nanospheric carbon. Laser fluence is used to control the degree of restructuring. A flame-based oxidation process treats the post-annealed carbon as an aerosol stream to remove unc

In the work presented here, flame conditions are tailored to create a synergy between various metallic additives (cobaltocene, nickelocene, cobalt acetylacetonate, and ferrocene) and the flame environment to synthesize the desirable product of single
