In this study, we produced ZnO nanoflakes (ZnO-Nfs) by using microwave-assisted techniques. The structural properties of ZnO-Nfs were analyzed by x-ray diffraction (XRD) technique, Raman scattering spectroscopy and field-emission scanning microscopy (FESEM). The Crystallite size (D) and lattice constants of ZnO-Nfs were calculated. The optical properties of ZnO-Nfs were investigated by using UV-visible diffuse reflectance spectrum and photoluminescence (PL) spectra. Also, dielectric constants of ZnO-Nfs were calculated as related to the refractive index (n) an extinction coefficient (k).
