Comb-shaped Au electrodes are prepared on ceramic substrate firstly, and then the one dimensional nanostructure is synthesised by hydrothermal method in order to get ZnO UV detector. The effect of the concentration of solution on the growth of nanostructure ZnO and UV sensitivity has been studied. X-ray diffraction patterns indicate that the product is pure phase zinc oxide. The morphology of one dimensional nanostructure is characterized by SEM. The diameter of one dimensional nanostructure ZnO obtained is 80～500nm. Test shows that the UV conductivity properties of ZnO are affected by their surface topography.
