Effect of Molar Concentration on Structural, Morphological and Optical Properties of CdO Thin Films Prepared by Chemical Bath Deposition Method
Öz
Cadmium Oxide (CdO) thin films were grown on Indium Tin Oxide (ITO) coated glasses by Chemical Bath Deposition (CBD) technique. The concentration of aqueous bath was varied between 0.03 M and 0.05 M. The films were annealed at 400 °C for 2 h. Structural, morphological and optical properties of the CdO thin films were investigated with XRD, SEM and Uv-Vis measurements. Additionally, the hydrophobic and hydrophilic nature of the films were studied with the water contact angle (WCA) measurements. The CdO thin films showed cubic crystal phase diffraction peaks in the spectra. The surface of CdO thin films changed from prism-like morphology to network-like (nano-fibrous) morphology with increasing concentration. The optical band gaps of thin films were calculated between 3.816-3.857 eV by Uv-Vis spectra. The Prisma- like morphology exhibited maximum transmittance above 65%. Nature of the CdO thin film surface changed from hydrophobic to hydrophilic, depending on changing morphology with increasing the precursor concentration.

Kimyasal Banyo Biriktirme Metodu ile hazırlanmış CdO İnce Filmlerin Yapısal, Morfolojik ve Optik Özellikleri Üzerinde Molar Konsantrasyonu Etkisi
Öz
Kadmiyum Oksit (CdO) ince filmler, farklı konsantrasyonlardaki solüsyonlar kullanılarak İndiyum Kalay Oksit (ITO) kaplamalı camlar üzerine Kimyasal Banyo Biriktirme (CBD) yöntemi ile sentezlenmiştir. CdCl2’nin sulu banyosunun konsantrasyonu 0.03 M ile 0.05 M arasında değişmektedir. Filmler 400 °C ‘de 2 saat tavlanmıştır. CdO ince filmlerin yapısal, morfolojik ve optik özellikleri araştırılmıştır. Ek olarak, filmlerin hidrofobik ve hidrofilik yapısı, su temas açısı (WCA) ölçümleriyle çalışılmıştır. Bütün filmler kübik kristal yapıdan elde edilmiş, ancak ince filmlerin yüzey morfolojisi artan konsantrasyon ile, prizma benzeri yapılardan ağsı (nano lifli) yapılara dönüşmüştür. Optik bant boşluğu Uv-Vis spektrumları kullanılarak değerleri 3.816-3.857 eV aralığında hesaplanmıştır. Prizma benzeri morfoloji %65 üzerinde maximum geçirgenlik göstermiştir. Konsantrasyonun artmasıyla, CdO ince filmlerin yüzey doğası, morfolojide meydana gelen değişikliklere bağlı olarak hidrofobik yapıdan hidrofilik yapıya dönüşmüştür.
