“…Furthermore, this change is due to the difference in the sizes of Al and Zn ions. 31 According to Yan et al 32 our d-spacing UV-visible spectroscopic results and band gap tuning.-The optical absorption of the synthesized nanoparticles was investigated using UV-visible spectroscopy, and the band gap energy was calculated. This provides researchers with a practical method to investigate how doping impacts the optical absorbance and band gap of pure zinc oxide nanoparticles.…”

We report the effect of Aluminum (Al) doping on the properties of zinc oxide (ZnO) nanoparticles. Sol-Gel method was used to synthesize the pure and Al-doped ZnO nanoparticles. Al doping was done at three different concentration 3%, 5%, and 7%. Presence of Al, Zn, and O was confirmed by energy-dispersive X-ray (EDX) analysis and X-ray photoelectron spectroscopy (XPS). The crystal structure and morphologic analysis of prepared nanoparticles using X-ray diffraction, field-emission scanning electron microscopy, and transmission electron microscopy-selected area energy diffraction techniques. Increase in the doping concentration has reduced the average crystallite size considerably in the range 18-14 nm. The optical properties have been studied using UV–Vis spectrophotometer. The UV–Vis spectroscopic studies showed that Al was incorporated into ZnO lattice as Al3+ due to the decreasing optical band gap of nanoparticles. The XPS and EDX analysis is done to confirm the elemental composition of the pure and Al doped ZnO nanoparticles. The addition of suitable doping agent will lead towards the improvement of structural as well as optical properties. The variation in different properties due to the addition of Al as a dopant is also studied.

“…To address these issues, researchers have explored various approaches to modify ZnO-NPs' properties. One such approach is doping, which involves the intentional introduction of impurities into a crystal lattice [6,9,[24][25][26]. Dual doping is a promising technique that can enhance a limited portion of sunlight and improve the optical properties of ZnO-NPs.…”

“…Dual doping is a promising technique that can enhance a limited portion of sunlight and improve the optical properties of ZnO-NPs. Doping can also minimize the energy bandgap, thereby enhancing ZnO's antioxidant and antimicrobial properties [14,[26][27][28]. Te introduction of a limited amount of foreign materials, such as biomolecules and transition metals (Mn, Fe, Cr, and Cu) at the nanoscale, can increase and modify the surface area of ZnO-NPs, improving their functionality and efciency [5,6,9,29].…”

Zinc oxide nanoparticles (ZnO-NPs) are used in various fields such as industrial, environmental remediation, catalytic, and antibacterial applications. However, their ability to absorb visible light is limited due to their high-energy bandgap and fast electron-hole recombination, which restricts their use. To enhance the efficiency of ZnO-NPs in medical and other applications, surface functionality can be modified through doping. Here, we investigated the effects of S and N doping on the energy bandgap of ZnO-NP and their antimicrobial and antioxidant activities. The results showed that the optical bandgap energy of pure ZnO-NPs was 2.98 eV while that of 6% N-ZnO, 4% S-ZnO, and S4-N6-ZnO was 2.78, 2.69, and 2.63 eV, respectively. The energy bandgap reduction is attributed to the changes in the electronic level of zinc oxide as the result of doping. The crystal size of pure ZnO-NPs, 6% N-ZnO, 4% S-ZnO, and S4-N6-ZnO was 29.06, 27.05, 29.02, and 25.06 nm, respectively, as calculated from XRD data using FWHM. Following the bandgap and particle size reduction, the antimicrobial activities of the dual-doped ZnO-NPs surpassed that of the pure ZnO-NPs. Moreover, dual doping improved the antioxidant activity of ZnO-NPs from 52.45% to 88.89% for the optimized concentration. Therefore, incorporating S and N as dual dopants can enhance the functionality and efficiency of ZnO-NPs in various fields.
