Abstract
The solvothermal process was employed to grow ZnO nanorods at low temperature onconducting substrate, which is extremely important for making efficient electrical contactsin various applications based on ZnO nanorods. Efforts were made to find the idealgrowth parameters for better alignment of the ZnO nanorods with a view to tailortheir luminescent properties. The ZnO nanorod arrays were characterized byscanning electron microscopy (SEM), transmission electron microscopy (TEM),energy dispersive analysis of x-rays (EDAX) and x-ray diffraction study. The ZnOnanorod arrays were found to have excellent UV emission properties at roomtemperature. Aligned ZnO nanorod arrays exhibit good field emission properties,revealing their applicability as cathode materials for field emission based devices.
