Hot Copper Plate Assisted Synthesis of ZnO Nanoflakes by Cost Effective Modified Spray Pyrolysis Method and its Structural, Morphological & Optical Studies

Zinc oxide (ZnO) nanoflakes have been synthesized by a simple and inexpensive Hot Copper Plate assisted and modified Low Cost Simplified Spray Pyrolysis Method using Zinc acetate dihydrate as host precursor source. The structure, optical properties and morphologies of ZnO nanoflakes have been characterized by X-ray diffraction (XRD), UVVis spectrophotometry, photoluminescence spectrophotometry (PL), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray analysis (EDAX). The FESEM reveal the formation of ZnO nanoflakes. XRD shows the hexagonal structure of the ZnO nanoflakes. Strong blue shift absorption is observed from the UVvis spectrophotometry. This blue shift indicates the quantum confinement of the ZnO nanoflakes. The enhanced luminescence property is measured from PL spectrophotometry.
