Komuro et al prepared Ce doped calcium barium phosphate by conventional solid-state synthesis; they found that the doping by Ce 3+ , Si 4+ enhanced the luminous intensity due to the combination to form Ca 6 BaP 4 O 17 phase [3] . N. Aisah et al studied Ce-doped ZnO, and they showed that there is no diffraction peaks of the phases containing Ce were found in the samples which indicated that Ce 3+ ions substituted or accommodated in ZnO lattice structure [4] .

Two weight percents of ceria (40 and 80 wt%) were added to tricalcium phosphate to improve some properties for Ce doped β-TCP by RF sputtering method on stainless steel substrate as coating for biomedical applications. The sputtering was done at 150 W and 150 o C. The confirming of doping was achieved by some techniques such as XRD, FESEM/EDS and EDS mapping, and indicated the occurring of incorporation between cerium oxide and TCP as thin film. Biocompatibility and antibacterial test was improved after adding cerium oxide to TCP which candidate the prepared thin film for bio implants. Microhardness also examined for prepared composites to show the increasing microhardness of CeO 2 /TCP coatings compared with conventional HA coating.

“…The red-shift in the absorption band of the ZnO nanostructure corresponding to improving the absorption of the photocatalysts was achieved by silver doping [13]- [14]. Besides that, the cerium doped ZnO nanostructure decreased band gap energy from 3.37 eV to 3.18eV, decreased size of nanorods, and increased the green emission peak in photoluminescence spectra [15]- [16]. In addition, Al doped ZnO nanostructures was also enhanced free charge carriers resulting in increasing electrical property [22]- [23].…”

The Zn1-xAlxO nanorod (NR) were grown on ITO substrates by a hydrothermal process. The influences of the Al doping concentration on the surface morphology, structural, optical, and electrical characteristics of the Zn1-xAlxO NR/ITO composite film were investigated in detail. The results indicated that characteristics of the Zn1-xAlxO NR/ITO composite film were strongly influenced by the Al doping concentration. Furthermore, the lowest vertical resistance of the Zn1-xAlxO NR can be obtained when x = 0.01 and it strongly reduces when the concentration of UV light illumination increases. This reduction follows an exponential decay with a decay rate of 4.35. This result shows good photoconductivity response of the Zn1-xAlxO NR/ITO composite film and its ability to apply for optoelectronic devices material.

“…The structural, morphological and optical properties of ZnO NPs can be improved and controlled by a chemical reaction which is a very crucial factor influencing the performance of semiconductor nanomaterials for many technological applications. Recently, great efforts have been made in the fabrication of doped ZnO nanomaterials in order to improve the morphological, structural and optical properties of nanomaterials specifically by modifying the surface properties such as electronic band gap, specific surface area, oxygen vacancies and crystal deficiencies [6,7]. In previous articles, it has been reported that doping with non-metal elements such as C, S and N can improve the structural, morphological and vibrational properties of ZnO [7][8][9].…”

It is very important to find new methods for improving the properties of nanostructured materials that can be used to replace the highly expensive and complicated techniques of fabricating ZnO nano-powders for solar cell applications. Pneumatic spray pyrolysis method offers a relatively inexpensive way of fabricating ZnO nanomaterials of controllable morphology, good crystallinity and uniform size distribution, which makes it a good candidate for the production of ZnO nanoparticles. Additionally, it has the advantage of producing ZnO NPs in one step directly on the substrate without the need for other wet chemistry processes like purification, drying and calcination. To that end, the present study emphasizes more on the design and optimization of spray pyrolysis system as well as on the pneumatic spray pyrolysis conditions for the production of carbon-doped ZnO nanoparticles. The un-doped and carbon-doped ZnO NPs were prepared using pneumatic spray pyrolysis employing zinc acetate as a precursor solution and tetrabutylammonium as a dopant. The fabricated un-doped and C-ZnO NPs were characterized for their morphological, structural and optical properties using SEMEDX, XRD and DRS. SEM analysis has revealed that the fabricated un-doped and C-ZnO NPs have spherical shape with mesoporous morphology. The crosssectional SEM has also revealed that the film thickness changes with increasing dopant concentration from 0.31 to 0.41 μm at higher concentrations. Moreover, the EDX spectra have confirmed the presence of Zn and O atoms in the PSPsynthesized ZnO NPs. XRD analysis of both un-doped and C-ZnO has revealed the peaks belonging to hexagonal Wurtzite structure of ZnO. Additionally, the DRS has revealed a decrease in energy band gap of the synthesized ZnO NPs, with the increase in carbon dopant level.
