In this contribution, we introduce a one-pot, rapid solvent-free method for preparation of silver iodide nanoparticles (AgI NPs). The AgI NPs were characterized by X-ray powder diffraction patterns (XRD), energy dispersive X-ray spectroscopy (EDX), diffuse reflectance spectra (DRS), scanning electron microscopy (SEM) and dynamic light scattering (DLS). The XRD data indicated a wurtzite structure of the beta-phase of AgI in the synthesized NPs. The EDX analysis confirmed the formation of a 100% pure AgI compound. The SEM images and the DLS data confirmed the nanosized spherical morphology of 25-70 nm. The DRS of the AgI nanoparticles showed a band gap about 2.7 eV.
