“…The optical band gap of the undoped CdO film was found to be 2.23 eV and it is lower than that of pure CdO film prepared by chemically spray and spray pyrolysis methods [33,34]. Further, it increases to 2.58 eV with increasing Mn dopant (up to 6% Mn).…”

“…Conductivity and transmittance are inversely proportional to each other and should be as high as possible for effective usage. The figure of merit is widely used to compare the performance of various transparent conductors as first defined by Haacke 22) is, Φ = Tr10/Rs where Tr is the optical transmittance for the range of 400-800 nm and Rs is the sheet resistance.

Transparent and conducting thin films of Ta-doped SnO 2 were fabricated on a glass substrate by a pulse laser deposition(PLD) method. The structural, optical, and electrical properties of these films were investigated as a function of doping level, oxygen partial pressure, substrate temperature, and film thickness. XRD results revealed that all the deposited films were polycrystalline and the intensity of the (211) plane of SnO 2 decreased with an increase of Ta content. However, the orientation of the films changed from (211) to (110) with an increase in oxygen partial pressure (40 to 100 mTorr) and substrate temperature. The crystallinity of the films also increased with the substrate temperature. The electrical resistivity measurements showed that the resistivity of the films decreased with an increase in Ta doping, which exhibited the lowest resistivity (ρ~1.1 × 10 −3 Ω·cm) for 10 wt% Ta-doped SnO 2 film, and then increased further. However, the resistivity continuously decreased with the oxygen partial pressure and substrate temperature. The optical bandgap of the 10 wt% Ta-doped SnO 2 film increased (3.67 to 3.78 eV) with an increase in film thickness from 100-700 nm, and the figure of merit revealed an increasing trend with the film thickness.

“…Of these methods, the spray pyrolysis is unique and cost effective compared to other methods requiring high vacuum environment. It is one step method operating at atmospheric pressure with very short production time [12]. Spray pyrolysis has proved to be simple, reproducible and inexpensive, as well as suitable for large area applications.…”

The objective of this work is to study the influence of pyrolysis temperature on structural, surface morphology and gas sensing properties of the nanostructured SnO 2 thin films prepared by spray pyrolysis technique. These films were characterized for the structural, morphological and elemental composition carried by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrophotometer (EDAX). The information of crystallite size, dislocation density and microstrain is obtained from the full width-at half-maximum (FWHM) of the diffraction peaks. Effect of sprayed deposition temperature on H 2 gas sensing performance and electrical properties were studied using static gas sensing system. The sensor (T pyr . = 350 °C) showed high gas response (S = 1200 at 350 °C) on exposure of 500 ppm of H 2 and high selectivity against other gases The results are discussed and interpreted.
