【 摘 要 】

The effect of time and pH on ZnO nanoparticles were observed as prepared viamicrowave-assisted approach. Zinc acetate dihydrate Zn (CH3COO)2.2H2O used asprecursor and 2 Propanol as solvent, NaOH was used as pH controller. ZnO nanoparticles(band gap 3.91 ev) of size within the range 50 nm to 80 nm were obtained by controllingthe pH (6-8). Characterization techniques of synthesized samples were investigated by Xraydiffraction (XRD), UV Visible spectroscopy, Raman spectroscopy, scanning electronmicroscope (SEM). Porous structure of ZnO nanoparticles was clearly observed withagglomeration. Above-mentioned variables, influenced the shape and size of preparednanoparticles prominently. Briefly, the microwave irradiation technique with pH controlwas highlighted as quick, cheap and single step approach to control the morphology ofsemiconductor nanoparticles in present work.
