Controlling of the structural characteristics of ZnO nanomaterials by reaction pressure and reaction time

The most significant parameters affecting particle size and morphology in nanoscale powder production are the working temperature time. reduction leads to addition of new electrical, mechanical, chemical optical properties materials. nano ZnO special importance due its multi-dimensional applications fields industry, cosmetics, electronics, etc. Zinc oxide (ZnO) with various morphologies was synthesized by hydrothermal method at different temperatures (140, 180 220oC) times (12, 18 24 h). samples were characterized SEM, EDX, XRD UV-vis techniques.SEM EDX findings show that especially nanostructures have developed. pattern showed sample well crystallized a structure hexagonal wurtzite. energy band gap values found be 3.07, 3.10, 3.19, 3.17 3.13 eV, respectively.
