A simple way to prepare Cupric oleate capped AgI nanoparticles

Cupric oleate capped AgI (Cu(OA)2–AgI) nanoparticles were prepared by a simple method and they have good dispersibility in organic solvents. X-ray diffraction (XRD), transmission electron microscope (TEM), FTIR, X-ray photoelectron spectrometer (XPS) and ultraviolet-visible (UV–vis) spectrometer were used to characterize the Cu(OA)2–AgI nanoparticles. The results show that the mean size is about 80 nm; the modified reagent has been chemically bonded on the surface of AgI. In addition, new absorption peaks in the UV region appear.
