Abstract: | Zinc oxide nanorods have been grown by vapor–liquid–solid (VLS) catalytic growth. The optical properties and structures properties
of the grown ZnO nanostructures have been studied by photoluminescence, high resolution X-ray diffraction and scanning electron
microscopy. The results show that the formation of ZnO nanostructures is strongly influenced by the growth conditions and
used substrates. It was found that oriented ZnO nanorods are grown more easily on a substrate with a similar crystalline structure
as ZnO. By optimizing growth conditions, oriented-ZnO nanorods grown on Si(001) substrate with a diameter of around 300 nm
and lengths of 20 to 35 μm have been achieved, and they show excellent optical properties. Laser action has been observed
at room temperature by using optical pumping.
