Elektrokimyasal Depolama ile Üretilen Transparan Metal Oksit CdO Ve CdAlO İnce Filmlerinin Optik Parametrelerinin Karşılaştırılması

Öz

Bu çalışmada tek adımda elektrokimyasal depolama yöntemiyle CdO ve CdAlO ince filmleri üretilmiş ve temel optik parametreleri kıyaslanmıştır. Optik inceleme 300-700 nm dalga boyu aralığında gerçekleştirilmiştir. Optiksel analizler sonucunda CdAlO ince filminin CdO ince filmine göre yüksek dalga boylarında daha geçirgen ve düşük dalga boylarında ise soğurma kapasitesinin yüksek olduğu görülmüştür. Maksimum geçirgenlik (T%) CdO ince filmi için 43%, CdAlO ince filmi için 55%’dir. 300 nm de CdO ince filminin yansıma (R%) değeri 6.5% iken CdAlO ince filminin R% değeri 7.5% tir. CdO ince filminin maksimum soğurma katsayısı (α) değeri 1.9x106 m-1 iken CdAlO ince filminin maksimum (α) 2.9x106 m-1 dir. 300 nm de CdO ince filmin sönüm katsayısı (k), kırılma indisi (n), enerji band aralığı (Eg) ve optiksel iletkenlik (σ) değerleri sırasıyla 0.04, 1.26, 2.82 eV ve 5.9x1014 iken CdAlO ince filminin bu değerleri sırasıyla 0.07, 1.31, 3.11 eV ve 9.2x1014’tür. Bu sonuçlar neticesinde CdAlO ince filminin CdO ince filmine göre daha yüksek optiksel değerlere sahip olduğu görülmüştür.

Comparison of Optical Parameters of Transparent Metal Oxide CdO and CdAlO Thin Films Produced by Electrochemical Deposition

Abstract

In this study, CdO and CdAlO thin films were produced using a single-step electrochemical deposition method, and their basic optical parameters were compared. Optical analysis was performed in the wavelength range of 300-700 nm. As a result of the optical analysis, it was observed that the CdAlO thin film was more transparent at higher wavelengths and had a higher absorption capacity at lower wavelengths compared to the CdO thin film. The maximum transmittance (T%) was 43% for the CdO thin film and 55% for the CdAlO thin film. At 300 nm, the reflection (R%) value of the CdO thin film was 6.5%, while the R% value of the CdAlO thin film was 7.5%. The maximum absorption coefficient (α) value of the CdO thin film was 1.9x10⁶ m⁻¹, while the maximum α of the CdAlO thin film was 2.9x10⁶ m⁻¹. At 300 nm, the extinction coefficient (k), refractive index (n), energy band gap (Eg), and optical conductivity (σ) values of the CdO thin film were 0.04, 1.26, 2.82 eV, and 5.9x10¹⁴, respectively, while for the CdAlO thin film, these values were 0.07, 1.31, 3.11 eV, and 9.2x10¹⁴, respectively. Based on these results, it was concluded that the CdAlO thin film exhibited higher values compared to the CdO thin film.
