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 tek-fazlı 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 nanoparçacıklarının yapısal özelliklerini detaylı şekilde inceleyen bu çalışma, katkılı ZnO’ nun hem spintronik hem de diğer nanoteknolojik uygulama alanlarındaki potansiyel kullanımına önemli bir katkı oluşturabilir.

Anahtar Kelimeler

Co katkılı ZnO, X-ışını kırınımı, X-ışını soğurma spektroskopisi, Wurtzite yapısı
