Bu çalışmanın amacı nanoyapılı CdO filmlerin fiziksel özelliklerine tiyoüre konsantrasyonunun etkisini incelemektir. Bunun için farklı tiyoüre konsantrasyonlarındaki (%0, 0.5, 1 ve 2) dört seri CdO film soda lime cam altlık üzerine SILAR tekniği kullanılarak büyütüldü. Bu filmlerin morfolojileri, kristal yapıları ve optik özellikleri sırasıyla MM, XRD ve UV-visible spektroskopi teknikleri ile karakterize edilmiştir. MM görüntüleri tiyoüre konsantrasyonunun nanoyapılı CdO filmlerin yüzey morfolojilerini etkilediğini göstermektedir. CdO filmlerinin düzlemlerinin tercihli yöneliminin tiyoüre konsantrasyon değerine kuvvetle bağlı olduğunu XRD analizinden elde edilen sonuçlar ortaya koymaktadır. UV-vis analizinden, tiyoüre miktarı arttıkça CdO filmlerinin optik enerji bant aralığının (Eg) önce azaldığı ve daha sonra tekrar artan konsantrasyonla arttığı belirlenmiş ve bu enerji değerlerinin (2.25 - 2.13) eV aralığında olduğu bulunmuştur.
