“…Similar observations have been made by some authors regarding the variation in band gap values in chalcogenide thin films [20,21]. The reflectivity R, the refractive index n, and the extinction coefficient k of crystalline solids are related through the equations [22,23] www.pss-c.com ( 1) ( 1)…”

Polycrystalline CuInS 2 films have been grown by spray pyrolysis method at different substrate temperatures, a simple method which can produce low cost and highly absorbing samples. Optical characteristics of the CuInS 2 films have been analyzed using spectrophotometer in the wavelength range of 400 -900 nm. The absorption spectra of the films showed that this compound is a direct band gap material and gap values varied between 1.51 -1.80 eV, depending on the substrate temperatures. The refractive index n, extinction coefficient k and dielectric constants ε 1 and ε 2 were also discussed and calculated as a function of wavelength λ.

“…(9) the value of optical conductivity increases with increase of the AgNO 3 concentration indicating higher number of Ag nanoparticles generated at higher concentration. This increase due to creation of new local levels in the band gap, lead to facilitate the crossing of electrons from the valence band to these local levels to the conduction band, consequently the band gap decreases and the conductivity increase [15,24]. …”

Silver-Poly vinyl alcohol Ag/ PVA nanocomposite films were prepared by casting method at room temperature with different amount of AgNO 3 solution (0.001, 0.0015, and 0.002ml). The prepared nanocomposites were characterized using UV-VIS spectrophotometer and the optical properties were investigated in the wavelength range 300-800 nm. The absorption peaks showed a shift towards higher wavelength with increasing AgNO 3 concentration while the energy band gap and absorption edges shifted towards lower energies with the increase of AgNO 3 concentration.
