Abstract

Zinc oxide (ZnO) nanoparticle processed by coprecipitation method, hydrothermal autoclave and at low temperature using the same amount of reactant components is reported. XRD analysis at 2 Theta (10° - 60°) shows diffraction peaks of wurtzite hexagonal structured ZnO nanoparticles having the same international center for diffraction data (ICDD) No. 01-075-0576 for the three methods. AFM 3D microstructure images of the surface morphology and vertical displacement of the topographical histogram of the scan height were discussed. TEM analysis shows the cross-sectional image of the ZnO nanoparticle processed using different methods. XPS elemental analysis of the surface chemistry shows wide exciton binding energy of the n-type ZnO nanoparticles and is suitable for solar cell application. The three synthesis methods were reproducible and can be used complementarily for large scale production of materials for optoelectronic devices.
