Cerium oxide (CeO2) nanoparticle is major compound in rare earth family and has received significant attention to block ultraviolet radiation. The zinc oxide (ZnO) is known for its good absorption properties at visible range. The present work aimed to synthesis CeO2-ZnO core-shell (CS) nanostructures by surfactant assisted coprecipitation method with the objective to improve the absorption range through the control ZnO shell thickness. The crystalline nature, particle size and shell thickness of CS were studied using X-ray diffraction, dynamic light scattering and transmission electron microscopy, respectively. Finally, to explore the optical properties we used UV-visible and photoluminescence spectroscopies. The structural analysis confirmed well crystalline in nature without any impurities and the nanostructures exhibited both fluorite and wurtzite phases which confirmed the formation of CeO2-ZnO CS. The optical absorption spectra showed a strong band at 300 nm and the photoluminescence measurement was carried out at an excitation wavelength of 310 nm.
