Bu çalışmada TiO2 nanomalzemesine %1, %3, %5 ve %10 Ca eklenmiş numuneler sol jel döndürerek kaplama yöntemiyle üretilmiştir. Numuneler üretilirken, 1000 rpm’lik bir dönme hızı 30 saniyelik süresi kullanılarak işlemi gerçekleştirilmiştir. Kaplama 3 kez tekrarlanmıştır. Üretilen filmlerin UV-VIS spektroskopisi ile geçirgenliği absorpsiyon spektrumları alınmış optik bant aralığı hesaplanarak özel...
