abstract = {Sn-doped ZnO thin films with 0%, 0.5%, 1%, 1.5% and 2% Sn were
grown by spray pyrolysis method on glass substrates under
optimized conditions. High resolution Field Effect Scanning
Electron Microscopy characterization showed that the films
consist of hexagonal-like grains. A comprehensive study of the
optical properties was performed and the dispersion constants
were determined. The effect of Sn content on the optical band
gap and the optical constants (refractive index, extinction
coefficient, dielectric constants, and dispersion parameters)
was studied. These Sn-doped ZnO thin films are highly
transparent (73–93%) in the visible region. A blue shift of
the optical band gap, attributed to the Burstein Moss effect,
was observed for the Sn-doped films. All the optical
dispersion parameters depend on the Sn content of the films,
but were found to reach threshold values at a Sn content of
0.5%. These optical parameters are discussed in terms of the
single oscillator model. This study demonstrated that this
0.5% Sn-doped ZnO thin film has enhanced physical properties,
allowing its better integration in optoelectronic devices.}
