KOBALT KATKILI ÇİNKO OKSİT NANOPARÇACIKLARIN YAPISAL ÖZELLİKLERİNİN İNCELENMESİ
Bu çalışmada, katkısız ve Co (%1, %3 ve %5 ) katkılı ZnO nanoparçacıkları ucuz ve kolay biryöntem olan mekanik bilyeli öğütme tekniği ile üretildi. Elde edilen nanoyapılı ürünlerin kristalözelliklerini ve yerel atomik yapılarını belirlemek için X-ışını kırınımı ve sinkrotron-temelli X-ışınısoğurma spektroskopisi ölçümleri kullanıldı. Tüm örnekler için wurtzite yapısı gözlendi. X-ışınısoğurma spektroskopisi sonuçları, Co2+iyonlarının saptanabilir herhangi bir ikincil faz oluşturmadanZnO wurtzite örgüsündeki Zn2+ bölgelerine başarıyla geçtiğini açıkça gösterdi. Co katkılı ZnOnanoparçacıkların yapısal özelliklerini detaylı şekilde inceleyen bu çalışma, katkılı ZnO’nun hemspintronik hem de diğer nanoteknolojik uygulama alanlarındaki potansiyel kullanımına önemli bir katkıoluşturabilir.
