It is well known that the semiconducting materials, particularly semiconducting thin films, have significant physical and chemical properties which are often sharply improved by combining them in different proportions for making their alloys (or) compounds. A wide range of photoinduced phenomena exhibited by chalcogenide glasses make them suitable for a variety of optical applications, such as in the correction of spatial uniformity of filters or the fabrication of integrated optical components and devices like selective optical filters, couplers and modulators, and planar waveguides for soliton Kerr propagation for ultrafast optical application. This review is based on Ag and Sb doped chalcogenide thin films and their subsequent effect on various properties of the host matrix due to alteration in structure, bonding etc. The developments of these metal-doped thin films and their physicochemical aspects were also discussed.
