Description
Summary:This work presents the results of the first preparation (to the best of current knowledge) and investigation of ZrN nanoparticles. The particles were produced by laser ablation/evaporation and adiabatic expansion from zirconium nitride powder targets. The particle size could be varied by applying different seeding gas flows. The size distributions were fairly narrow with mean diameters from {/content/2BQ2RPRX1CMQLQB8/xxlarge9001.gif}2R{/content/2BQ2RPRX1CM Q LQB8/xxlarge9002.gif}=5.5 nm to {/content/2BQ2RPRX1CMQLQB8/xxlarge9001.gif}2R{/content/2BQ2RPRX1CM Q LQB8/xxlarge9002.gif}=6.5 nm. Compositional analysis by secondary ion mass spectrometry (SIMS) and transmission electron microscopy (TEM) revealed, that almost stoichiometric crystalline particles were formed. The in-situ optical transmission spectroscopy measurements yielded a single plasmon resonance in the visible spectrum.
