Lately, photocatalytic applications of ZnO nanorods are of greater interest in ecological defense applications. When mag- nesium is doped with ZnO, the properties of nanorods can be improved for sev- eral 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 nano- rods grown on the glass substrate. Fuzzy Logic Controller (FLC) has been used to calculate precise and accurate results as the FLC is based on human-like rea- soning. The analysis of the dependence of diameter and length of Magnesium (Mg) doped ZnO nanorods on different input parameters is done by fuzzy simu- lations and the simulated results are then compared with the calculations done using Mamdani’s model. An almost negligible percentage error is calculated be- tween the simulated and calculated values. As at nanoscale the size of the struc- ture is crucial, the results of this study demonstrate that the synthesis parameters can be easily optimized to get Mg doped ZnO nanorods of the desired size to be used in specified application purpose.

Nanomaterials have become broadly studied for the past few years due to their unique properties which are, surface and edge effect, minor size effect, improved surface-to-volume ratio, as well as quantum size effect. Through the fast development in nanotechnology, a large number of engineered nanomaterials have been smeared in agriculture, industry, service, food, and medicine [1]. Among numerous nano- materials that are semiconductors in nature, ZnO has gathered great attention due to 20 http://www.i-jes.org
