Abstract

The study and application of thin film technology is entirely entered in to almost all the branches of science and technology. Semiconductor oxide thin films are materials with numerous applications in electronic and optoelectronic devices as well as some other applications such as protective coatings, heat mirrors and catalysis. Transparent conducting oxide films have been widely used in the fields of flat panel displays, solar cells, touch panels and other optoelectronic devices owing to their high electrical conductivity and optical transmittance in visible region. Fe3+ doped tin oxide thin films were prepared by chemical spray pyrolysis synthesis and characterized by different spectroscopic techniques. The morphologies of prepared sample were analyzed by using SEM and TEM studies. Functional groups of the prepared sample were observed in the FT-IR spectrum. PL studies of Fe3+ doped SnO2 thin films exhibit ultraviolet and blue emission bands. CIE chromaticity coordinates were also calculated from emission spectrum of Fe3+ doped SnO2 thin films..
