abstract={Se<SUB>90</SUB>Cd<SUB>10-x</SUB>In<SUB>x</SUB> (x=2,4,6 &amp;8) thin films have been deposited onto a chemically cleaned glass substrate by thermal evaporation technique under vacuum. The effects of different doping concentration of In have been investigated X-ray diffraction technique has been employed to investigate the structural characterization of the films. X-ray diffraction measurement indicates that the Se<SUB>90</SUB>Cd<SUB>10-x</SUB>In<SUB>x</SUB> films possess polycrystalline structure. Absorption spectra measured at normal incidence in the wavelength range 400-1100 nm have been analyzed for the optical characterization of the thin films under consideration. The optical constants (absorption coefficient (¦Á), extinction coefficient (k)) and optical band gap E<SUB>g</SUB> have been calculated. The absorption coefficient (¦Á) is found to increase with photon energy. It has been found that extinction coefficient (K) decreases with increase in wavelength (¦Ë). Optical band gap (E<SUB>g</SUB>) has also been evaluated for the Se<SUB>90</SUB>Cd<SUB>10-x</SUB>In<SUB>x</SUB> thin films with different compositions. It has been found that optical band gap (E<SUB>g</SUB>) increases with In incorporation in Se<SUB>90</SUB>Cd<SUB>10-x</SUB>In<SUB>x</SUB> alloys.},
