Synthesis and Characterization of Copper (I) Iodide Nanoparticles via Chemical Route

Polycrystalline of CuI nanoparticles were prepared via convenient liquid-phase route from the Cu+-DMF solution precursor. A passivation layer of Cu+-DMF absorbed on the particle surface were responsible for the nanoparticles formation. The broadening of XRD patterns showed that the size of CuI particle is reduced. The TEM image showed the spherical and well-dispersed of CuI nanoparticlest. The absorbance spectra were decreased with the addition of water. FTIR spectra confirmed the presence of C=O, C=N and C=H bonds. From the SEM and XRD results, we confirmed that the DMF played role as a stabilizing agent.
