Thin flms of CeO2/ZrC ceramics nanostructures were fabricated using spray pyrolysis technique due to economy method, simple, easy fabrication and high equity. The CeO2 thin flms were synthesized with various contents (0.02, 0.04, 0.06 and 0.08)g/25 ml. The ZrC NPs have been added to the CeO2 nanoceramics with ratios are 12.5%, 25% and 37.5% by diferent concentrations are (0.02, 0.04, 0.06 and 0.08) g/25 ml. Structure and optical characteristics of CeO2/ZrC ceramics nanostructures were studied. Structure characteristics were examined using the optical microscope (100×). Optical characteristics were tested in the wavelength (300–800) nm. The results indicated that the absorption and optical conductivity CeO2 nanostructure were increased with the increase in ZrC nanostructure content. The absorption increased about 30.8% and optical conductivity increased about 17.3%. The energy gap of CeO2 nanostructure was decreased with rise in the ZrC NPs content about 34.5%. In addition, the electrical conductivity of CeO2 was rise as the ZrC NPs ratio rise. The fnal results showed that the CeO2/ZrC ceramics nanostructures can be utilized for various felds in the electronic and photonics applications.
