An ionic liquid of either 1-butyl-3-methylimidazolium tetrafluoroborate (BMImBF4), or 1-butyl-3-methylimadazolium hydrogen sulfate (BMImHSO4) was added to a water-in-oil micro emulsion to observe the effect of ionic liquids on the kinetics of forming silver iodide nanoparticles inside a reverse micelle template of Polyethylene glycol tert-octylphenyl ether (Triton X-100) surfactant.  The objective was to evaluate the effectiveness of ionic liquids to form nanoparticles of uniform size.  A time driven uv-vis absorbance measurement was used to approximate the relative population of nanoparticles with a size that corresponds with an exitonic peak of 420 nm.  The results show a faster increase in the relative population of nanoparticles as ionic liquid was used.  It is suspected that the presence of ionic liquids allowed a faster rate of intermicellar exchange of precursor ions which coupled with the ionic liquids.
