碩士 === 崑山科技大學 === 光電工程研究所 === 98 === In this thesis, ZnO nanorods were synthesized on the glass substrates in a solution of Zn(NO3)2．6H2O and HTMA at 90℃ The morphologies and microstructures of the ZnO films and nanorods are characterized by X-ray diffraction (XRD) patterns, atomic force microscopy (AFM), scanning electron microscopy (SEM), and photoluminescence (PL). First, the ZnO seed layer was deposited on glass structure by the RF sputtering system to study the effect of ZnO nanorods. The effects of different annealing temperature on the seed layer growth have been investigated in this study. The microstructure was investigated by glazing incident X-ray diffraction and high resolution transmission electron microscopy. The property of luminescence was measured by PL. Second, after the growth of ZnO seed layer, the substrate with ZnO seed layer is placed in the low temperature aqueous solution under different experimental conditions, which the aqueous solution of Zn(NO3)2•6H2O and C6H12N4 was prepared. The Zn(OH)2 would be supersaturated, and ZnO nanorods would be precipitated and grown on seed layer. The effects of aqueous solution with different concentration on the growth of ZnO nanorods investigation including surface morphology and microstructure was carried out by XRD, SEM and AFM measurements. Also, optical properties were determined by PL analyses.
