KOBALT KATKILI ÇİNKO OKSİT NANOPARÇACIKLARIN YAPISAL ÖZELLİKLERİNİN İNCELENMESİ

Bu çalışmada, katkısız ve Co (%1, %3 ve %5 ) katkılı ZnO nanoparçacıkları ucuz ve kolay bir yöntem olan mekanik bilyeli öğütme tekniği ile üretildi. Elde edilen nanoyapılı ürünlerin kristal özelliklerini ve yerel atomik yapılarını belirlemek için X-ışını kırınımı ve sinkrotron-temelli X-ışını soğurma spektroskopisi ölçümleri kullanıldı. Tüm örnekler için wurtzite yapısı gözlendi. X-ışını soğurma spektroskopisi sonuçları, Co2+ iyonlarının saptanabilir herhangi bir ikincil faz oluşturmadan ZnO wurtzite örgüsündeki Zn2+ bölgelerine başarıyla geçtiğini açıkça gösterdi. Co katkılı ZnO nanoparçacıkların yapısal özelliklerini detaylı şekilde inceleyen bu çalışma, katkılı ZnO’nun hem spintronik hem de diğer nanoteknolojik uygulama alanlarındaki potansiyel kullanımına önemli bir katkı oluşturabilir.

Investigation of the Structural Properties of Cobalt Doped Zinc Oxide Nanoparticles

In this study, pure and Co (1%, 3% and 5%) doped ZnO nanoparticles were fabricated through mechanical ball milling technique, which is an inexpensive and easy method. X-ray diffraction and synchrotron-based X-ray absorption spectroscopy measurements were used to determine the crystalline properties and local atomic structures of the obtained nanostructured products. A wurtzite structure was observed for all the samples. X-ray absorption spectroscopy results was clearly indicated that the Co2+ ions were successfully substituted into the Zn2+ sites of the ZnO wurtzite lattice without forming any detectable secondary phases. The present study, investigating the structural properties of Co doped ZnO nanoparticles in detail, could make a significant contribution to the potential use of doped ZnO in both spintronic and other nanotechnological applications.
