Simulation, synthesis and band-gap engineering of 2nd group doped ZnO nanostructures

Abstract

Nano-materials are considered as a fundamental constituent in almost every field of medical science to engineering. However, the field of application of nano-material largely depends on its structural, chemical and optical properties of nano-material. Doping of nano-materials results in changes their particle size and band-gap which effects its applications. In this work, the effect of change in band-gap and particle size has been studied for 2nd group element doped ZnO (Zinc Oxide) nanostructures synthesized on AAO (Anode Aluminum Oxide) template having a pore size of 180.5 nm fabricated using chemical bath deposition and Anodization respectively. Fuzzy logic rule based system is used to study the effect of 2nd group element doping in ZnO nano-structure fabricated on AAO template with a fix pore size on the band-gap and output nanostructure. With addition of 2nd group element in ZnO nano-structure, a variation in rod length and band-gap has been observed. A decrease of rod length and an increase in band-gap have been observed by the addition of 2nd group including Be, Mg, Ca and Sr elements in ZnO nano-crystal. The fuzzy logic results are in accordance with the experimental system which shows the effectiveness of the simulations.
