Nanostructured thin films have attracted the attention of an increasing number of researchers from several disciplines during the last decade, due to their outstanding electronic and optical properties and extensively useful applications in various optoelectronic devices. Nanocrystalline CdSe:FeSe thin films were deposited onto glass substrate by spray pyrolysis method at 573K temperature. The structure and surface morphology of the CdSe:FeSe thin films were characterized by X-ray diffractometry (XRD) and scanning electron microscopy (SEM). The CdSe:FeSe thin films are nanocrystalline in nature with hexagonal lattice. The optical band gap of CdSe:FeSe thin film is of the order of 1.95 eV.
