چکیده

The use of plant extract is generating the interest of researchers toward cost effective,
nontoxic, economic viability and eco-friendly green synthesis of nanoparticles. In the present
work, zinc oxide (ZnO) nanoparticles were synthesized using black tea extract and zinc nitrate
as the zinc source by the sol-gel method. The synthesized ZnO nanoparticles were
characterized by powder X-ray diffraction (XRD), UV-visible spectroscopy and Fourier
Transform Infrared Spectroscopy (FTIR). The average crystallite size of ZnO nanoparticles
was calculated using Scherrer formula. The X-ray powder diffraction (XRD) analysis
revealed the formation of wurtzite hexagonal phase ZnO with average particle size of 32 nm.
