“…The plasma frequency ωp is the resonance frequency of the free carriers and this optical parameter marks the transition from a dielectric to a metallic behavior in materials [24]. Based on the idea that the refractive index of the materials in the visible region is due to electron oscillation excitation between conduction and valence band (inter-band transitions and around the band edge) [25,26], Wemple and Di Domenico [26] have proposed a single effective oscillator to describe the dispersion of the refractive index:…”

In the present work we studied the effect of temperature and molarity on microstructural and optical properties of Ag3O4 thin films deposited by spray pyrolysis. Transparent conductive thin films of silver oxide (Ag3O4) were prepared by using an aqueous solution of silver nitrate (AgNO3) and sprayed onto heated soda glass substrate at 350 °C and annealed at 550°C. X-ray diffraction showed that the films have a monoclinic structure with a preferential orientation along the (031) direction. A visible shift of the main peak as a function of temperature and solution molarity is observed. The lattice parameters a, b and c are estimated to be 3.68, 9.30 and 5.20Ǻ respectively. Scanning Electron Microscopy (SEM) analysis shows that all films are nanostructured and homogeneous with dense surfaces. Transmittance and reflectance measurements are performed in the spectral range 200-1600 nm and yielded a band gap energy (Eg) varying in the range 3.07-3.25 eV. Refractive index was studied in terms of Moss, Ravindra and Herve–Vandamme models. The optical constants such as the oscillator energy (E0), static refractive index (n0), dispersion energy (Ed) and dielectric parameters (εr ) of the films were derived from the analysis and discussed.

“…The optical bandgap of this material was measured on single crystals yielding E g = 2.23 eV . For CuIn 7 S 11 films a significant dependence of the optical properties from the film thickness was observed with values for E g = 2.30 eV ( d = 460 nm) and E g = 1.98 eV ( d = 290 nm) …”

Solvothermal syntheses of copper-indium-sulfides performed with different Cu:In:S ratios afforded crystallization of nanocrystalline Cu-In-S phases with compositions close to CuInS 2 , CuIn 3 S 5 , and CuIn 7 S 11 . Each sample shows a different and distinguishable morphology. The minority component CuInS 2 with wurtzite-type structure crystallizes as thin plates, which are preferably stacked parallel to black stacks.
