“…However, increasing the aluminum concentration further has increased the green emission with respect to the NBE emission. This has been shown to occur in Al:ZnO when zinc vacancies are created during the doping process as well as oxygen vacancies created by the substitution of zinc atoms with Al leading to enhancement of the green emission [28,29]. Table 1 shows EDX results from all samples to determine atomic percentage of elements in the sample.…”

Random lasing was demonstrated from aluminum doped ZnO nanorods fabricated on ITO coated glass substrates using simple chemical deposition technique. Different Aluminum (Al) doping parameters were explored in an attempt to realize low threshold ZnO random lasers. Results confirm threshold was strongly dependent on doping concentration and suggestive of resonant coupling with Al in lowering the threshold by 2 orders of magnitude when compared to undoped ZnO nanorods. Lowest threshold was obtained from ZnO nanorods doped with 10 mM of aluminum, suggesting best doping concentration for ZnO random lasers formed by nanorod array. Results further indicate possibility of controlling random lasing properties by adjusting the doping concentration.

Titanium dioxide (TiO2) thin films of different concentrations are prepared by using titanium trichloride on conducting FTO glass substrate by chemical bath deposition (CBD) method. The X‐ray powder diffraction (XRD) method is used to study the structure of TiO2 thin film. XRD analysis has confirmed amorphous nature of the TiO2.The surface morphology of the film is studied using field emission scanning electron microscopy (FE‐SEM). The optical properties are studied using the UV‐VIS and photoluminescence (PL) spectroscopy. The band gap of prepared titanium dioxide (TiO2) thin film is 2.84 eV. A photo‐electrochemical cell analysis shows that the conversion efficiency of 3.24% with a fill factor of 43%.

Adhesion force is one of the most important factors in microelectromechanical systems (MEMS), especially for microassembly. It depends on operating conditions and is affected by the contact area. In this study, the adhesion force between MEMS materials and AFM tips was analysed using AFM's point-mode spectroscopy. The aim was to study the effectiveness of various coatings in MEMS adhesion surfaces.For this purpose, five silicon surfaces were used, four of which were coated, and one was noncoated. Two of them were deposited by single-layer coating (Au and Ag). The other two were deposited by double-layer coating (TiO 2 /Au, TiO 2 /Ag) on a Si (1 0 0) substrate. The depositing was accomplished by the thermal evaporation method. Composite materials and analysis were reviewed by observing the SEM image. The experimental results showed that the method of deposition helped to decrease the adhesion force between the probe tip and the surface of the specimens, and double-layer coating had stronger effect on decreasing the adhesion force than the single-layer coating.
