“…54 However, this emission probably consisted of several emissions around this area as the peak became wider with the doping of Mg ions. 55 The other emission was at wavelength ∼ 440 nm (2.82 eV blue emission), according to several reports, this emission originates from the defect emission of interstitial zinc (Zn i ). 43,[56][57][58] The shift of these emission with the Mg doping concentration was insignificant, which suggested that this state might formed during the annealing process.…”

Magnesium (Mg) with a concentration range of 1 to 3 at% was successfully doped in zinc oxide (ZnO) and prepared via a hydrothermal process in powder form. X-ray diffraction patterns revealed a polycrystalline nature of the prepared powders. Images taken by a scanning electron microscope showed that the synthesized powders had clear solid hexagonal rod structures. Furthermore, the solid hexagonal structures were hollow because of the Mg ions introduced into the ZnO. The photoluminescence emission of the undoped and Mg-doped ZnO showed an enhancement of the ultraviolet emission with the Mg concentrations. Furthermore, the Gaussian fitting reveals that the UV band emission is consist of two emissions. The first peak was at 3.36 eV for the undoped ZnO that shifts to 3.4 eV, 3.43 eV for the 1 at% Mg and 2 at% Mg concentration, respectively. Thereafter the UV peak position reduced to 3.39 eV for the 3 at% Mg ions concentration. The results were studied, and the correlation of the results was attributed to the doping process.

“…Once the Mg ions are incorporation in the ZnO lattice, an expand in the energy bandgap of ZnO is emerged. 55 The peak was further shifts with 2 at% Mg ions incorporation to the value of 3.43 eV. The shift in the UV energy can be as a result of two different factors, namely quantum size effect or the modifications in the bandgap.…”

<p class="PARAGRAPH">ZnO nanorods have been extensively studied owing to their exceptional materials properties as well as outstanding performance in optics, electronics, and photonics. Lately, photocatalytic applications of ZnO nanorods are of greater interest in ecological defense applications. When magnesium is doped with ZnO, the properties of nanorods can be improved for several potential applications in diverse fields of science and technology. In this work, we have studied the effect of parameters like doping concentration and temperature for solution-based growth on the diameter and length of the nanorods grown on the glass substrate. Fuzzy logic controller has been used to calculate precise and accurate results as the fuzzy logic system is based on human-like reasoning. The analysis of the dependence of diameter and length of Mg doped ZnO nanorods on different input parameters is done by fuzzy simulations and the simulated results are then compared with the calculations done using Mamdani’s model. A percentage error that is almost negligible is calculated between the simulated and calculated values. </p>
