“…The XRD data show that all peaks of diffraction match with pure ZnO in the typical JCPDS card 36-1451 pattern and crystallized into the hexagonal ZnO structure with P63mc space group and lattice parameters of a = 3,25 Å and c = 5,21 Å. The peaks show no secondary phases in the cobalt-doped ZnO whichis in excellent accord with the literature[36]. Zooming on the major peaks (Fig.1.B) revealed a significant shift and broadening in all peak positions toward a higher angle relative to undoped ZnO as cobalt concentration increased.…”

“…The mean crystallite size varies from 32.6 nm for undoped ZnO to 34.8 nm for 10% cobalt-doped ZnO. The lattice parameters (a and c) have been determined using Bragg's law for the hexagonal system [36]. Table 2 shows the estimated lattice parameters for ZnO and cobalt-doped ZnO films.…”

“…Next, the samples are dried in air (3 rd step in one SILAR cycle) and rinsed with DW (4 th step). The deposition process by the SILAR method was described earlier by Soltabayev et al Chemical reactions associated with the growth of ZnO have also been reported in other studies . The ZnO and TZO samples are prepared with 40 SILAR deposition cycles.…”

In this study, Ti-doped ZnO films with flower−rod-like nanostructures were synthesized by the successive ionic layer adsorption and reaction (SILAR) method for enhanced NO gas-sensing applications. The stoichiometric ratio of Ti in the host ZnO lattice was confirmed by atomic absorption and energy-dispersive X-ray spectroscopies. All of the synthesized films exhibited a pure wurtzite hexagonal structure that seemed to deteriorate at high Ti doping contents as was manifested by the measured X-ray diffraction patterns. Scanning electron microscopy images of ZnO revealed the coexistence of porous flower-and rod-like structures, which became finer, denser, and more compact with Ti doping. By UV−vis measurements, the transmittance of the synthesized pure ZnO thin film in the visible region (∼75%) increased by about 10% with Ti doping, and the energy band gap seemed to decrease up to some limit of Ti content. Among the fabricated sensors (based on pure ZnO, 1% Ti-doped, 3% Ti-doped, and 5% Ti-doped ZnO films), the best sensing performance was observed for the 1% Ti-doped ZnO film. At first, this was associated with its high density of oxygen vacancies present on the surface of the film and ionized oxygen vacancies present in the ZnO lattice (confirmed, respectively, by X-ray photoelectron and photoluminescence spectroscopies). Nonetheless, this may also be due to its increased crystallinity (confirmed by X-ray diffraction and photoluminescence spectroscopy), high area-to-volume ratio (confirmed by scanning electron microscopy images), high specific surface area (confirmed by Brunauer−Emmett−Teller measurements) as well as high mobility and carrier concentration (confirmed by Hall measurements). The sensor was highly selective to NO gas and showed notable stability as well as very short response and recovery times, which makes it eligible for the early detection of any indoor or outdoor NO gas leakages.

“…Al-doped ZnO films, known as AZO, have attracted the attention of the research community for their interesting, enhanced properties and large surface/volume ratio, which make them favorable for the fabrication of various nanometric optoelectronic and optical devices. They also serve as a cheaper alternative to indium tin oxide (ITO) transparent electrodes [12]. Diverse scientific reports have pointed out their exceptional high electrical conductivity [13,14], which has been proven to affect the NLO behavior.…”

Simultaneous interrogation of pump and probe beams interacting in ZnO nanostructures of a two-wave mixing is proposed for dual-path data processing of optical signals by nonlinear optical effects. An enhancement in third-order nonlinear optical properties was exhibited by Al-doped ZnO thin films. Multiphoton absorption and nonlinear refraction were explored by the z-scan technique at 532 nm with nanosecond pulses. The evolution of the optical Kerr effect in the ZnO thin films was analyzed as a function of the incorporation of Al in the sample by a vectorial two-wave mixing method. Electrical and photoconductive effects were evaluated to further characterize the influence of Al in the ZnO solid samples. Potential applications of nonlinear optical parameters for encoding and encrypting information in light can be envisioned.
