“…Most prepared ZnO had mainly one-dimensional and twodimensional morphologies in the current literature, and the multidimensional morphology of ZnO was seldom reported; [17][18][19] moreover, ZnO only reacts in the ultraviolet region due to its nature, so researchers adopted doping modication to expand its application in visible light. [20][21][22] Nithya et al 23 introduced Mn doped nano-sized ZnO, which was prepared by a chemical precipitation method, and the results showed that the band gap of Mn doped ZnO was obviously reduced, and the degradation of BG dye solution reached 97.47% under solar light, which showed outstanding photocatalytic performance. Wang et al 24 reported the ower-like ZnO doped with Ce and the results showed that the photocatalytic effect under solar irradiation was 80.56% higher than that of pure ZnO.…”

“…PL analysis showed that incorporation of indium into the clean ZnO matrix increases the level of Zni and VZn defects inducing a broadening in the NBE emission. Other report [10] investigates Bi+3 effects on ZnO film's photoelectrical parameters. In this study, how photo-current generation mechanism of Bi +3-doped the film work was investigated.…”

Changes in growth conditions of ZnO thin films produced in the presence of different oxygen, changes in important properties such as crystal, surface properties, and absorption properties of the films were examined and reported. It is inferred from the XRD experimental results that the oxygen we applied to the films plays a role in the crystal structure changes of the films (grain size, strain value, dislocation density, etc.). The highest value of RMS roughness of the film is 8.58 nm and the lowest value of RMS roughness of the film is 1.08 nm, which corresponds to non-flow and 1 sccm flow film, respectively. AFM proved that films with nano-structured, tightly packed, grain properties were obtained in the produced films. Inference from UV analysis made is that the oxygen applied to the film caused small changes in the optical band gap values (in the range of about 3.30-3.32 eV). Except for 3 sccm oxygen state, all the films obtained were tightly packed, granulated and almost homogeneous and the nano property was clearly seen. All the results obtained show that the oxygen applied in the ZnO film process causes some changes in the physical properties of the film and this has an effect on the film quality and it is seen that these results can contribute to the production of ZnO thin filmbased Light Emitting Diodes (LEDs).

Microstructure modifications on thin photoelectrical properties refers to changes in the microscopic structure of thin films that affect their ability to convert light into electricity. This study investigates the deposition and post-treatment effects in the electric and visual qualities of GZO, IZO, and ZnO thin layers, aiming to enhance their applicability in electronic and optoelectronic devices, according to the X-raydiffraction (XRD) examination. Thin films were deposited on glass substrates using magnetic sparking at thicknesses of 300 nm and 500 nm, followed by treatments like wet aging and annealing at 220 °C. The results showed significant improvements in crystallinity and optical characteristics, with ZnO films exhibiting a preferred (003) orientation. IZO films demonstrated notable mobility at 10.96 cm2/V-sec and resistivity of 2.49×10⁻3 ohm-cm. The novelty of this research is the novel integration of wet aging and low-temperature annealing, that notably improves thin film efficiency while maintaining structural integrity. The findings indicate that post-treatment significantly enhances the properties of these thin films, suggesting their potential for various electronic applications.
