Spin-Coating tekniği ile hazırlanan nano yapılı yarı iletken ZnO ince filmlerin
optik sabitleri ve dispersiyon enerji parametreleri optik karakterizasyon
yöntemi kullanılarak belirlendi. ZnO ince filmlerinin yasak enerji aralığı 3,08-3,25
eV arasında bulunmuştur. ZnO ince filmlerinin kırılma indisi dağılımı, tek salınım
modeline uymaktadır. ZnO ince filmlerin dispersiyon enerjisi ve osilatör enerji
değerleri sırasıyla 6,46-9,85 eV ve 4,82-5,54 eV aralığında bulundu. ZnO ince
filmlerinin dielektrik sabitinin reel ve sanal kısımları belirlendi. ZnO ince
filmler için e₂ eğrileri bir pik
vermektedir ve bu pik, elektronların valans bandından iletim bandına foto
uyarılmasından kaynaklanmaktadır.
