The optical and electronic properties of aluminum-doped zinc oxide (AZO) thin films on a glass substrate are investigated experimentally and theoretically. Optical studies with coupling in the Kretschmann configuration reveal an angle-dependent plasma frequency in the mid-IR for p-polarized radiation, suggestive of the detection of a Drude plasma frequency. These studies are complemented by oxy...

Either metal/metal or metal/non-metal co-doping is one of the most effective methods to modulate visible emission ZnO. In this paper, ZnO, aluminum-doped ZnO (Al-ZnO), aluminum and silver co-doped (Al/Ag-ZnO), nitrogen (Al/N-ZnO) are deposited. Combining substitution zinc ions using Al and/or Ag doping oxygen N expected introduce more interstitial vacancy defects related light in films. The res...

Spin-coating technique is employed to deposit nanostructured zinc oxide (ZnO) doping aluminium (Al) on p-Si substrate. Atomic forces microscopy (AFM), X-ray diffraction (XRD), ultraviolet–visible (UV–Vis) and scanning electron microscopies (SEM) are utilized investigate the influence of annealing temperature in range 200 600°C morphological, optical, structural topographical characteristics Al ...

   ZnO structures with different dopants (1mol% Cr, Mn, Fe, Co, Cu and Ni) have been synthesized via a simple hydrothermal method using sucrose as a template. These doped ZnO nanostructures characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL). The photocatalytic property of these synthesized materials was studied by a pho...

The laser-initiated thermal (optothermal) switching of cholesteric liquid crystals (CLCs) is characterized by using different azobenzene (Azo) derivatives and laser wavelengths. Under 405-nm laser irradiation, Azo-doped CLCs undergo phase transition from cholesteric to isotropic. No cis-to-trans photoisomerization occurs when the 405-nm laser irradiation is blocked because only a single laser i...

Thin film of zinc oxide was prepared by spin coating on pyrex glass using zinc acetate dehydrate, 2methoxyethanol and monoethanolamine (MEA) as a precursor, solvent and stabilizer respectively. Also, Aluminium-doped thin film of ZnO was prepared by using AlCl3. Deposited thin films were investigated for structural and optical properties using X-ray diffraction (XRD) and UV–VIS-NIR spectrophotom...

In this work, research was carried out to analyze the possibility fabricate nanostructured antireflection coatings based on ZnO. The dependence of structural features film substrate heating temperature during deposition an aluminum-doped zinc oxide (AZO) has been studied. It is shown that it impossible obtain required properties by changing one parameter, material, in range 20 – 600 °C. For pur...

Zinc Oxide and Al-doped ZnO (AZO) thin films were prepared by Electrostatic spray deposition method on soda lime, glass substrates. The effects of substrate temperatures (300, 350, 400 and 450 C) on the Structural properties of the films were investigated. X-ray diffraction analysis indicates that the films were polycrystalline, having hexagonal (Wurtzite) structure irrespective of their substr...

We have investigated the influences of aluminum and gallium dopants (0 to 2.0 mol%) on zinc oxide (ZnO) thin films regarding crystallization and electrical and optical properties for application in transparent conducting oxide devices. Al- and Ga-doped ZnO thin films were deposited on glass substrates (corning 1737) by sol-gel spin-coating process. As a starting material, AlCl3⋅6H2O, Ga(NO3)2, ...
