چکیده
Bu çalışmada, farklı derişimlerde (A1: 0,8 Molar, A2: 1,25x10-2 A3: 2,5x10-3 Molar) hazırlanan çözeltilere 2 şer kez 5 saniye daldırma metodu (Dip-coating) ile cam lameller üzerine TiO ince filmleri üretilmiştir ve üretilen bu filmler 500 °C’ de tavlanmıştır. Genel olarak amorf yapıya sahip filmlerin 2θ = 25,5° (1 0 1) Miller yönelim pikinde yayılma görülmüştür. Derişimin azalması küçük taneli yapılar, küresel şekilden daha irili ufaklı elipse doğru değişim göstermiştir. UV bölgede yansıtma özelliği oldukça fazla iken 400-700 nm görünür ise geçirgenlikleri fazladır. A1, A2 A3 derişimli enerji bant aralığı değerleri sırası Eg 3,52 eV; 2,60 eV 3,03 hesaplanmıştır. artması elektriksel özdirenç değerlerinin artması, oksit alt tabakalardaki özel iletkenlikten dolayı metal benzeri tipik bir davranış gösterdiğinin kanıtıdır.
