Abstract
Tin Oxide (SnO2) thin film is one of the important transparent conducting oxides and
applied in various fields such as in solar cells, optoelectronic devices, heat mirror, gas sensors, etc due
to its electrical and optical transparency in visible light spectrum. Co2+ doped tin oxide thin films were
prepared by chemical spray pyrolysis synthesis and characterized by different spectroscopic
techniques. Powder XRD data revealed that the crystal structure belongs to tetragonal rutile phase and
its lattice cell parameters, average crystallite size were evaluated. The morphologies of prepared
sample were analyzed by using SEM and TEM studies. Vibrational bands of the prepared sample were
observed in the FT-IR spectrum.
