Co Katkılı SnO2 Numunelerinin Sentez ve Karakterizasyonu

Öz

Yüksek kristalleşmeye sahip katkısız ve Co katkılı SnO₂ numuneleri başarılı bir biçimde hazırlandı. Co içeriğinin SnO₂’nin termal ve morfolojik özellikleri üzerine etkileri araştırıldı. Co ilavesiyle Kristal büyüklüğünde ve birim hücre parametrelerinde değişimler tespit edildi. Co ilavesiyle faz bileşimi değişmedi. Hem X-ışını kırınımı hem de Fourier dönüşümlü kızılötesi sonuçları her bir numune için SnO₂ fazının oluşumunu doğruladı. Üretilen numunelerin oda sıcaklığından 900 °C’ye kadar termal kararlılığı gözlendi. Morfoloji Co içeriğinden etkilendi ve enerji dağılımlı X-ışını sonuçları SnO₂ yapısı içerisine Co’ın nüfuz ettiğini doğruladı.

Synthesis and Characterization of Co-Doped SnO2 Samples

Öz

The un-doped and Co-doped SnO₂ samples having high crystallinity were successfully prepared. The effects of Co content on the structural, thermal and morphological properties of SnO₂ were investigated. Changes in the crystallite size and unit cell parameters were detected with adding of Co. The phase composition did not alter with the addition of Co. Both X-ray diffraction and Fourier transform infrared results confirmed the formation of the SnO₂ structure for each sample. The thermal stability of the as-produced samples from room temperature to 900 °C was observed. The morphology was affected by Co content, and energy dispersive X-ray results verified the introduction of Co into the SnO₂ structure.
