Axial Growth

The ZnO nanorods were fabricated on top of the seeded gold layer by the aqueous solution method with the solution of zinc nitrate and hexamethylenetetramine (HTMA) at 90°C for 24 hours. The variety of the ZnO nanorods were prepared and investigated based on the precursor concentrations, in a range of 1 to 40 mM. The physical morphologies and crystal structures were characterized by field-emission scanning electron microscopy (FE-SEM) and X-ray diffractometry (XRD), respectively. The results showed that, with the small precursor concentrations, the lateral growth of the nanorods was highly significant when compared to their axial growth. The precursor concentration of 20 mM was best optimized for the preparation of the ZnO nanorod arrays with the hexagonal structures at the highest rod diameter and length. At the higher concentrations, although the nanorod size remained nearly constant, the length was however rapidly decreased. Further analyses also proved that, with the increased precursor concentrations, the number density of the ZnO nanorods was progressively increased along with the more complete hexagonal wurtzite structures.

The substrate effects on the morphology and photoluminescence (PL) properties of ZnO nanorods synthesized by a low temperature solution method has been investigated. ZnO seed layers on the substrates were prepared by radio-frequency sputtering. ZnO nanorods have been characterized by PL spectra and field emission scanning electron microscopy (FESEM). FESEM results showed that the nanorods grown on the polyethylene terephthalate (PET) substrate had the most uniform size and the highest coverage density compared with the Si and glass substrates. PL measurements showed that the ZnO nanorods grown on the Si substrate had the best performance that may be attributed to higher crystallization and the low density of defects in the ZnO nanostructures. These findings have shown that the morphology and PL of ZnO nanorods strongly depend on the substrate.

Aqueous Solution Method

Large quantity of free-standing ZnO nanorods and nanowalls were synthesized at low temperature of below 100 °C using zinc acetate, zinc nitrate hexahydrate, and hexamethylenetetramine by using a simple aqueous solution method. The general morphology of the grown ZnO nanostructures which include nanorods and nanowalls was strongly influenced by growth conditions. It was found that the grown ZnO nanorods are of a single-crystalline hexagonal structure and preferred c-axis growth orientation. ZnO nanorods were of better crystallinity than ZnO nanowalls, due to the higher growth temperature used to grow ZnO nanorods. Strong free exciton emission bands with relatively weak deep level emission were clearly observed from ZnO nanorods and nanowalls, indicating their good optical properties.
