The Zinc Oxide (ZnO) nanofluids were prepared by the one-step solvothermal method. The crystal structure and average crystallite size of the ZnO nanofluids were determined by X-ray diffraction pattern. The morphology and particle size were studied using the scanning electron microscope (SEM) and transmission electron microscopy (TEM). Dynamic light scattering (DLS) is used to calculate the particle size of the ZnO nanofluids. UV-Visible absorption spectrum is used to analyze the optical property of the ZnO nanofluids. The thermal conductivity properties of ZnO nanofluids were examined.
