Abstract

We have formed nanoparticles of Si, C, Ti, and Fe by pulsed laser ablation and have explored the feasibility of passivating these particles during the synthesis process in order to minimize particle coarsening. Passivation was done by forming the nanoparticles in an Ar/N₂ background, which allowed the formation of a thin nitride layer on the nanoparticle surface. In this paper we describe the synthesis procedure for synthesizing and passivating the nanoparticles. The characterization results indicate the nanoparticle synthesis in N₂ does not significantly affect agglomeration.
