Growth and properties of electrodeposited transparent Al-doped ZnO nanostructures

Synthesis and characterization of Mg-doped ZnO thin-films electrochemically grown on FTO substrates for optoelectronic applications

“…The XRD data indicated also that the (002) peaks of MZO lms was declined as Mg concentration increased concurrently with the broadening of the full-width-half-maximum (FWHM), caused a slender loss in the lms crystallinity. 23 In addition, very accurate inferences indicated a shi in (002) peak position of XRD spectra of MZO thin lms towards higher 2q angles with the increase of Mg doping content as can be seen in Fig. 3b.…”

“…This was believed to be attributed to the ion migration ability improvement and the hydroxyl ions (OH À ) production near the surface of the substrate, both of which are in favor of the formation of ZnO. [21][22][23][24] The CV data revealed also that the onset of a cathodic current occurred at more positive potentials in the Mg containing electrolytes. Such behavior is very similar to the Langmuir type adsorption observed in the catalytic role of Zn 2+ ions in nitrates reduction by Yoshida et al 25 The CV analysis provided, thus, strong evidence that Mg 2+ is analogous to Zn 2+ and other metallic cations adsorbing onto the electrode surface and acting as a catalyst for the reduction of nitrates ions in aqueous solutions as shown in Fig.…”

“…The generated metal hydroxide were dehydrated spontaneously into zinc oxide as described in eqn (2) at suitable temperature baths with high pH value. [21][22][23] NO 3(aq)…”

“…Electrochemical deposition method is the most effective since it is capable to perform doping incorporation and control the electrical and optical properties of lms by monitoring and adjusting the deposition conditions as well as the different ion proportions in the electrolyte solutions. [21][22][23] Aer adjusting these parameters, high-quality undoped and Mg-doped ZnO thin lms were successfully deposited on uorine-doped tin oxide (FTO) substrate by the ECD technique. The inuence of doping with Mg on the electrochemical, structural, optical, morphological and electrical properties of the electrodeposited thin lms systematically investigated, and the obtained results are discussed in detail in this report.…”

Study the electronic properties in a ZnO cluster with the substitution of Aluminum to form Al- ZnO

“…The results of Hall resistance and mobility as a function of concentration explain this effect [22]. The morphology of the crystalline structure is affected by aluminum acting as nucleation centers [23].…”
