Tin-doped nickel oxide thin films have been successfully prepared by spray pyrolysis technique on glass substrates at 460°C. The effects of tin doping on structural, optical, and electrical properties were investigated. X-ray diffraction pattern reveals that all prepared thin films have cubic structure with (111) preferred orientation. The surface topography of these films was performed by atomic force microscopy. Optical measurements show a high transparency in the visible range around 95%. The optical band gap Eg decreases with Sn content from 3.633 to 3.54 eV. PL measurements show some bands transition which shift irregularly with Sn doping. Finally, the electric conductivity of NiO thin film was investigated through the impedance spectroscopy measurements in the frequency range 5 Hz-13 MHz at various temperatures. These measurements show a thermally activation of the electric. AC conductivity of NiO thin films is investigated through Jonscher law. Also, from these measurements, dielectric parameters were calculated.

“…Several characterization techniques such as XRD, optical spectra, and hardness investigations have been applied to differently thick obtained samples [23][24][25][26]. The thickness-dependent performance of the different as-grown layers has been additionally investigated in terms of mechanical, optothermal and microhardness behaviours.…”

Recently, metal oxide nanolayered semiconductors revealed their increasing usefulness as UV detectors and transparent conductors in optoelectronic devices. In the present paper, a simple fabrication process has been carried out to prepare layered TCO compounds with different controlled thicknesses. Conjoint physical investigations allowed discussion of the validity of optimality in terms of geometrical parameters. A synthetic function based on pondered physical parameters was a practical guide to reach optimality.

In 2 O 3 : Eu thin films were successfully grown by spray pyrolysis. XRD studies showed that the films had In 2 O 3 cubic structure with (004) preferential orientation and best crystal properties at 1.5% Eu doping level. The optical band gap energy decreased with Eu content around 4.1 eV. Urbach energy was of the order of 278 meV, it decreased with Eu content which indicates a decrease in the defects by doping. The dispersion of the refractive index was discussed. Raman spectroscopy showed the band positions corresponding to In 2 O 3 cubic phase with a small shift related to europium incorporation within In 2 O 3 matrix. PL measurements showed a large band which was located at 410 nm and related to the band-to-band transitions and other bands related to impurity levels. Finally, the electric conductivity was investigated depending on the effect of temperature. Activation energy was found to range from 45 to 60 meV for films which were prepared with 1% Eu content.
