What is Dielectric Properties of Zinc Oxide Nanoparticles Using Annona Muricata Leaf about?

Present investigation aims the synthesis and characterization of Zinc oxide (ZnO) nanoparticles using Annonna Muricata leaf by means of safe, non-toxic, and ecofriendly green method. Structure and crystallite size of the product were examined by X-ray Diffraction analysis (XRD). XRD analysis reveals crystalline nature with hexagonal wurtzite structure in the space group of P63mc having average crystallite size of 21 nm. Peak at 418 cm -1 in Fourier Transform Infrared Spectra (FTIR) corresponds to Zn-O stretching which confirm the formation of ZnO nanoparticles. High Resolution Transmission Electron Microscopy (HRTEM) shows irregular shape particles. Ring nature of Selected Area Diffraction (SAED) pattern indicates poly crystalline nature. UV-Visible spectrum shows a characteristic absorption peak of ZnO nanoparticles at wavelength of 350 nm having optical band gap of 3.14 eV. The morphological characterization of synthesized nanoparticles was done by Field Emission Scanning Electron Microscopy (FESEM) shows agglomerated nanostructures. Energy Dispersive X-Ray analysis (EDX) confirm ZnO nanoparticles with Zn and O atoms. Dielectric measurements have been carried out on sintered pell
