“…8). The optical gap is ranged from 1.4 to 1.6 eV, this is in the same order than the reported values in the literature [28,29]. However, film prepared at flow rate of 25 ml/h have an optical band gap close to 1.4 eV required for solar cells since it matches well with solar spectrum.…”

“…Therefore, deposition parameters effect has been widely studied and optimized in order to produce CuO thin films with suitable properties for the application in hand. The most studied parameters are: precursor concentration [25] substrate temperature [26,27] and doping [28,29]. However fewer studies have been devoted to the influence of solution flow rate in ultrasonic spray pyrolysis technique.…”

ZnO lms were deposited on glass substrates by ultrasonic spray pyrolysis technique at a substrate temperature of 300 ± 5• C. All of the lms have been annealed at 500• C temperature for dierent time (1, 2, and 3 h) to improve the optical, electrical and surface properties. The eect of annealing time on the lms of physical properties has been investigated. UV-Vis spectrophotometer has been used for transmittance measurements. Also, band gap values of the lms have been determined by optical method. Atomic force microscopy has been used to have information the surface morphology and roughness values of the lms. Thicknesses, refractive index and extinction coecient values of the lms have been determined by spectroscopic ellipsometry technique. The electrical conduction mechanisms and resistivity of the lms were investigated using two probe technique. After all the investigations it was concluded that annealing time has a dramatic eect especially on the surface, optical properties and electrical resistivity values of ZnO lms. From the results of these investigations, the application potential of the lms for solar cell devices as transparent electrode was searched.

“…Among all the techniques co-precipitation is a low process cost, low temperature of heat treatment, high yield, controllability, reproducibility, vacuum-free usage, and wide possibility to varying properties by changing the composition of the solution, etc. The physical and other properties of these TCO's are controlled by doping metals such as aluminium [14], indium [15], fluorine [16], zinc [17], nickel [18], magnesium [19] and also with certain rare earth elements. CdO is not as popular as that of its counterpart ZnO, thou it has interesting properties and potentialities.…”

Undoped cadmium oxide along with samarium doped CdO are synthesized by simple soft precipitation method. Resulting precursor was calcined at 400°C for 2 h. As a result of heating, a pure material was produced. The obtained compound possesses a cubic crystalline structure at nanoscale. Also, FESEM image showed that the resulting material is composed of nanoparticles and its size decreases with increase of Sm doping relative with the particle size calculated from XRD. The photoluminescence shows the emission of violet and blue colour peaks and the peak at 468 nm which is responsible for a better antibacterial activity. The synthesized nanopowders are subjected to two different gram positive (Staphylococcus aureus and Enterococcus faecalis) and two different gram negative (Escherichia coli and Klebsiella pneumoniae) bacterial strains respectively. It is noted that there are high activity of the Sm doped CdO towards gram negative bacteria.
