| Summary: | 碩士 === 雲林科技大學 === 光學電子工程研究所 === 98 === In this study, ZnO seed layer was deposited on glass structure by the RF sputtering system, and then nanorods arrays were prepared by low temperature aqueous solution aqueous solution reaction concentration, temperature, time process Variables on structure of ZnO nanorods, the morphology and composition of the ZnO nanorods was observed using Field-emission scanning electron microscopy (FE-SEM) show that the aspect ratios of the ZnO nanorods are enhanced when the concentration is decreased and the temperature is increased, the Energy dispersive spectrometers (EDS) show that Atomic(%) of zinc content are enhanced when the concentration and time are increased , Atomic(%) of oxide content decreased, Atomic(%) of zinc content more than the oxygen atoms, the X-ray diffraction (XRD) patterns show that ZnO nanorods arrays were similar XRD patterns indicating the nanorods in high crystallinity, indicating excellent orientation in the c-axis direction, PL spectra show that the green/uv ratios decreased when ration concentration is increased, multi-stage increased the ZnO nanorods surface area and DSSC efficiencies, ZnO/TiO2 structure increase in dye adsorption, improve DSSC efficiency.
