Abstract

anosystem morphology control is proving to be vital for developing nano technologies. This control allows for the optimization of a nanoparticle’s optical and electrical properties. One form of control is the addition of defects during nanocrystal formation. Nanoprisms are highly responsive to this form of control through halide concentration. However, the rate at which this control occurs has remained relatively unexplored. The formation kinetics of silver nanoprisms were monitored before, during, and after crystal formation as a function of halide concentration. The standard deviations between multiple replicates were found to be too large for this method to reach conclusions about the kinetic control of nanoprism formation. However, the subset of bromide ions in the concentration range (2.00 μM–3.33 μM) showed statistical independence through non-overlapping standard deviation between concentration sample groups. This may indicate that refinement of this method may yield similar results in the other concentration ranges or halide types.
