Abstract

Pure nano-magnesium oxide (MgO) layers with bombardment spacings of (0.5, 1, and 1.5 cm) and doped with nano-cerium oxide (CeO₂) at three percentages (0.1, 0.2, and 0.3%) with a spacing of 1 cm were prepared using PLD. Initial samples were prepared by mixing the raw powders and pressing them in a hydraulic press with a diameter of 10 mm at a pressure of 5 tons for 10 minutes. They were then placed in a laser device for fragmentation and deposition on glass substrates. The structural and optical properties of the deposited films were studied. XRD results indicated that the resulting phase of MgO and CeO was cubic, while the composite of both materials after doping was Mg,CeO₃ with a monoclinic crystal system. The optical results showed that the energy gap increased continuously with each nano addition, and the highest energy gap was reached at the ratio of 0.3% CeO₂, amounting to 3.807 eV, while the transmittance values were 80%, and the absorbance decreased slightly at the same addition ratios.
