“…Accordingly, ultraviolet detectors have gained great importance for monitoring the environment and also in the military fields [19]. Many wide band gap nanomaterials including TiO 2 [20], NiO [21], SnO 2 [22], MoS [23], ZnTe [24], ZnSe [25,26], ZnO [27], SiC [28] and Nb 2 O 5 [29] has been used as a detectors for UV radiation. Among these materials Zinc oxide has proven, through many studies over a long period, its high efficiency in detecting ultraviolet radiation.…”

In this work pure and Ni-doped ZnO thin films have been deposited onto glass substrates using the spray pyrolysis technique. All films were deposited at constant deposition parameters but the Ni content was changed from 0 to 7 weight (wt) %. XRD results revealed the formation of a hexagonal ZnO phase whilst no other phases were detected. The crystallite size was determined using Scherrer's equation and found to be 45.9 nm for the pure film. Scanning electron microscope images show the formation of irregular grains with a broad size distribution. The existence of Ni in the deposited films was confirmed using energy dispersive spectroscopy (EDX), where the Ni content in the film increases as the weight % increases in the starting solution. The optical band gap was determined and found to be 3.3 eV for the pure ZnO films, which was reduced with Ni doping. The performance of the deposited films for UV radiation has been examined for the 365 nm wavelength and at different applied potentials and constant power. The rise and decay times for doped films were observed to exhibit faster rise/recovery as compared to pure films. The minimum response time was found to be 0.09 s for Ni-7wt% film and the minimum decay time is 0.07 s for Ni-1wt%.

“…It is critical to determine which element or elements ZnO must be doped with in order to control the bands gap, conductivity, carrier's concentration and applications. Because of the potential uses in spintronics, several researchers have recently focused on doping levels ZnO with incorporating transition metals (TMs) such as Co, Mn, Cu, Ni, Fe, and Cr [1][2][3][4][5][6][7][8][9][10]. Copper is nearly optimal for changing the properties of ZnO among the other doping elements due to the atoms of copper possesses a radius and electronic shell similar to zinc atoms; thus, replacing zinc with copper does not result in a modification in the lattice constant.…”

The influence of copper doping on the magnetic fields, photoluminescence, crystalline structure, transmittance, and band gap of ZnO films produced through magnetron sputtering RF, magnetron sputtering DC, pulsed laser deposition, sol-gel methods and spray pyrolysis, it has been extensively studied [8][9][10][11][12][13][14][15].…”

Using a spray pneumatic technique, cobalt (Co) and copper (Cu) co-doped zinc oxide thin films were effectively deposited on a glass substrate. The goal of this work was to create a semiconductor with good optical and electrical properties by co-doping ZnO thin films with Cu and Co. The ZnO thin films obtained from the Co and Cu co-doping exhibit patterns of x-ray diffraction spectra that suggest they are hexagonal ZnO (wurtzite, JCPDS 36-1451). The thin film elaborated with 2 % Co and 7 % Cu has the lowest value of crystallite size (D = 14.67 nm). The transmission spectra demonstrate that all films have good optical transparency in the visible spectrum, with 7 % Cu achieving the highest transmission. Increasing Cu contents raised the band gap energy. The value at the minimum was 3.31 eV. The optical band gap’s broadening is a significant characteristic of advanced materials and may be useful in applications involving metal oxide nanostructures for visible light gas sensing.

Aerosol‐assisted chemical vapor deposition (AACVD) was used to deposit highly transparent and conductive titanium or fluorine‐doped and titanium‐fluorine co‐doped ZnO thin films on glass substrate at 450 oC. All films were characterized by X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), UV‐Vis spectroscopy, scanning electron spectroscopy (SEM), and four‐point probe. The films were 600‐680 nm thick, crystalline, and highly transparent (80‐87%). The co‐doped film consisted of 0.70 at.% titanium and 1 at.% fluorine, and displayed a charger carrier mobility, charge carrier concentration, and a minimum resistivity of 8.4 cm2 V‐1 s‐1, 3.97 x 1020 cm‐3, and 1.69 x 10‐3 Ω cm, respectively. A band gap of 3.6 eV was observed for the co‐doped film. Compared to the undoped and singly doped films, the co‐doped film displayed a notably higher structure morphology (more homogenous grains with well‐defined boundaries) suitable for transparent conducting oxide applications.
