Zn0.4Cd0.4 Kompozit Malzemesinin Üretilmesi ve Karakterizasyonu

ZnO-CdO kompoziti hidrotermal yöntemle hazırlandı. Nanokompozitin yapısal, morfolojik, optik ve elektriksel özellikleri X-ışını kırınımı (XRD), FTIR, taramalı elektron mikroskobu (SEM), UV-VIS-NIR spektrofotometre ve iki prob yöntemi kullanılarak gerçekleştirilmiştir. Termal kararlılığı belirlemek için TG-DTA analizi yapıldı. Bileşim analizi EDX ile yapıldı. Kompozitin optik bant aralığı, Zn prekürsörünün içeriğinin arttırılması ile birlikte sırasıyla 2.84 eV olarak bulunmuştur.

Zn0.4Cd0.4 COMPOSITE FABRICATION AND CHARACTERIZATION

ZnO-CdO composite was prepared with hydrothermal method. The structural, morphological, optical, and electrical properties of the nanocomposite have been carried out using X-ray diffraction (XRD), FTIR, scanning electron microscopy (SEM), UV-VIS-NIR spectrophotometer, and two probe, respectively. TG-DTA analysis was done to determine the thermal stability. The compositional analysis was done by EDX. The band gap of the composite were found to be 2.84 eV.

Keywords:

Hydrothermal method, Optical band gap, TG-DTA, Zinc oxide,
