Özellikle, çevre dostu yöntemlerkullanılarak nanoyapılı malzemelerin üretilmesi nanoteknoloji için daha da önemli hale gelmiştir. Çinko oksit(ZnO) nanoteknoloji için öne çıkan malzemeden bir tanesidir. Bu çalışmada, siyah çayın (Camellia sinensis) suluekstraktı kullanılarak ZnO nanotanecikleri üretildi ve döndürerek kaplama sistemi ile bir cam altlık üzerine incefilm olarak kaplandı. Üretilen ZnO örneğinin tanımlanması ve kristal özelliklerinin belirlenmesi x-ışını difraksiyonu(XRD) ile gerçekleştirildi. XRD verilerinden ZnO örneğinin ortalama kristal boyutu 44 nm olarak hesaplandı. ZnOörneğinin morfolojik özellikleri alan emisyonlu-taramalı elektron mikroskobu (FE-SEM) ile incelendi ve ortalamatanecik boyutu yaklaşık 100 nm olarak ölçüldü. Üretilen ZnO örneğinin optik özellikleri mor ötesi-görünür bölge(UV-VIS) spektrofotometresi ile incelendi ve 350-1000 nm dalgaboyu aralığında % 90 üzerinde optik geçirgenlikgözlendi. Üretilen ZnO örneğinin elektriksel iletkenlik değerleri dört nokta dc sistemi ile ölçüldü ve sırasıyla 35 ve550 °C ölçüm sıcaklıklarında 1.65*10-8 ve 1.26*10-6 Ω-1.cm-1 olarak belirlendi.

In particular, the productionof nanostructured materials via environmentally friendly methods has become even more important fornanotechnology. Zinc oxide (ZnO) is one of the few materials that stand out for nanotechnology. In this study, ZnOnanoparticles were produced using black tea (Camellia sinensis) aqueous extract and coated on a glass substrateby a spin coating system. X-ray diffraction (XRD) system was used to characterize the produced ZnO sample anddetermine its crystal properties. The average crystal size of ZnO sample was calculated to be 44 nm from XRDresults. Morphological properties of produced ZnO sample was examined by field emission-scanning electronmicroscopy (FE-SEM) and the average particle size was measured as about 100 nm. The optical properties of theproduced ZnO sample were investigated by ultraviolet-visible region (UV-VIS) spectrophotometer and opticaltransparency was over 90 % in the range of 300 to 1000 nm. The electrical conductivity values of the producedZnO 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 themeasurement temperatures of 35 and 550 °C, respectively.
