Abstract

Nanotechnology is an important field of research in materials science. In particular, the production of nanostructured materials via environmentally friendly methods has become even more important for nanotechnology. Zinc oxide (ZnO) is one of the few materials that stand out for nanotechnology. In this study, ZnO nanoparticles were produced using black tea (Camellia sinensis) aqueous extract and coated on a glass substrate by a spin coating system. X-ray diffraction (XRD) system was used to characterize the produced ZnO sample and determine its crystal properties. The average crystal size of ZnO sample was calculated to be 44 nm from XRD results. Morphological properties of produced ZnO sample was examined by field emission-scanning electron microscopy (FE-SEM) and the average particle size was measured as about 100 nm. The optical properties of the produced ZnO sample were investigated by ultraviolet-visible region (UV-VIS) spectrophotometer and optical transparency was over 90 % in the range of 300 to 1000 nm. The electrical conductivity values of the produced ZnO sample were measured by four probe dc system, and determined to be 1.65*10-8 and 1.26*10-6 Ω-1.cm-1 at the measurement temperatures of 35 and 550 °C, respectively.
