Abstract

Our efforts to nucleate and grow AgI nanoparticles in Sb-doped Ag thin films by a closed chamber ambient iodization process has been delineated. The Ag-Sb thin films are characterized by XRD to be nanocrystalline; Sb prolongs the iodization process by delaying the nucleation of AgI nanoparticles, so that optimization of concentration, thickness and iodization duration yields films with self-assembled nanoparticle structure. The retarded growth of AgI particles is reflected in the slow but controlled evolution of the exciton band and variation in the Sb concentration dependent cluster density directly seen in the SEM micrographs.
