“…2b-e, the small particles were observed over the surface of the particles. These small particles are known as uncus (Alemi et al 2013), and were formed as a result of layered growth. It was also observed that due to increase in doping value, the number of uncus particles and heterogeneity in particle size were also increased.…”

The thin films of cadmium zinc selenide (Cd 0.5 Zn 0.5 Se) were prepared over glass substrates by chemical bath deposition technique. The Cd 0.5 Zn 0.5 Se thin films were doped with Gd at various doping values. The structural, morphological, compositional and optical properties were examined by XRD, SEM, EDX, UV-visible absorption and photoluminescence studies, respectively. Various structural parameters were calculated and the band gaps for these thin films were estimated and found in the range of 2.19-1.79 eV with respect to increasing doping values.

“…In this technique, characteristics of films relying upon preparation conditions similar to spray rate, nozzle-substrate and the substrate temperature [11]. CdO is one of material considered to be a model n-type semiconductor [12], with cubic structure where each ions collared by six ions of different electric charge [13,14]. In this work, the variation of the optical, structural properties of CdO thin films obtained by spray pyrolysis method was studied as a function of the Ce doping with various concentrations.…”

Transparent thin films of CdO:Ce has been deposited on to glass and silicon substrates by spray pyrolysis technique for various concentrations of cerium (2, 4, and 6 Vol.%). CdO:Ce films were characterized using different techniques such as X-ray diffraction (XRD), atomic force microscopy(AFM) and optical properties. XRD analysis show that CdO films exhibit cubic crystal structure with (1 1 1) preferred orientation and the intensity of the peak increases with increasing's of Ce contain when deposited films on glass substrate, while for silicon substrate, the intensity of peaks decreases, the results reveal that the grain size of the prepared thin film is approximately (73.75-109.88) nm various with increased of cerium content. With a surface roughness of (0.871–16.2) nm as well as root mean square of (1.06-19.7) nm for glass substrate, while for silicon (84.79-107.48) nm, for a pure CdO and doped with Ce (2, 4, and 6 Vol.%). The 300-nm-thin CdO films showed that the optical energy band gap equal 2.6 eV, and increases with increasing doping until reaches a maximum value of 3.25 eV when doping levels 6 Vol.%.

CdO thin films have been deposited by Spray Pyrolysis Technique (SPT) on a glass substrate. The structural and optical properties of thin films are studied at different annealing temperatures 100, 200 and 300 C o . By using X-Ray Diffraction, XRD patterns indicated that films are polycrystalline in nature and cubic phase with preferred orientation along the plane (111). The optical properties using UV-VIS spectroscopy show that the direct band gaps decreased from (3 to 2.75) eV with increasing the annealing temperature from(100-300)C o , this decreasing could be ascribed to increase of the localized states available in band gap which referred by Urbach , s energy value.
