عنوان انگلیسی Preparation and Characterization of Perfume Spray-Coated CdO Thin Films: Substrate Temperature Effect
چکیده انگلیسی مقاله Cadmium oxide (CdO) thin films were produced in this study utilizing a spray pyrolysis approach using a perfume atomizer at varied substrate temperatures. The cubic crystal structure of the CdO was shown by XRD analysis. The size of the crystallites, dislocation density, and microstrain were determined and studied. All samples exhibit a sharp shift in transmission, indicating a straight transition and high crystallinity. In the wavelength range 400 nm - 800 nm, raising substrate temperature from 200 - 300 °C increases film transmission by up to 45 - 58%. The band gap Eg is calculated and found to be between 2.23 and 2.40 eV for the substrate temperature of 200 – 300°C. Scanning electron microscopy and energy-dispersive X-ray spectra were used to determine morphology and elemental composition, respectively. The photoluminescence spectra of the samples show violet to blue emission peaks centered around 439 nm. The films were found
to have good optical properties, making them ideal for optoelectronic applications.
