| Description | Journal: Materials Research Express The undoped and various magnesium (Mg) doped cadmium oxide (CdO) thin films were synthesized by spray pyrolysis technique. Structural, optical and morphological examinations of the samples were carried out via various instruments. X-ray diffraction (XRD) and Raman spectroscopic measurements of the samples were performed to obtain structural properties. Ultraviolet (UV)-visible and photoluminescence (PL) spectroscopy measurements as well as scanning electron microscopy (SEM) were employed to characterize optical and morphological properties of the undoped and Mg doped CdO thin film. XRD measurements revealed that both undoped and Mg doped CdO thin films, demonstrate a cubic structure and have preferential orientations along the (200) plane. In the Raman spectrum, it was observed that the peak (266cm-1) of the first peak belonging to CdO disappears and the second main peak (908cm-1) shifts to higher energies together with the Mg dopant. As a result of the absorbance measurements, the band range of the samples showed a shift of the band gap from 2.15 eV to 2.43 eV with the Mg dopant, and the Burstein-Moss effect showed a shift to gray scale and decreased from 67% to 59% in transmittance measurements. The PL results shown that both undoped and Mg doped CdO thin films had a UV emission of 394 nm (3.15 eV), blue emission of 434 nm (2.86 eV), blue-yellow emission of 540 nm (2.30 eV), 735 nm (1.69 eV) and emission of 782 nm (1.59 eV). The SEM measurements have indicated that CdO thin films are turned from pyramidal structures to random shape with Mg dopant. |
