NOVELTY - A zinc oxide structure comprises zinc oxide crystal deposited in the crystal plane of a substrate by immersing the substrate having crystal plane comprising metal-containing material in a reaction solution such that the crystal plane becomes downward. The crystal plane of the zinc oxide structure is same as the surface orientation of the substrate. The zinc oxide structure has a zinc oxide crystal having an aspect ratio of one or more and a bottom radius of 250-450 nm, on the substrate.    USE - Zinc oxide structure is used for manufacturing zinc oxide particles (claimed) used for insulators, conductors, solid electrolytes, fluorescent display tubes, electroluminescent elements, ceramic capacitors, actuators, laser oscillation elements, cold cathode elements, ferroelectric random access memory, piezoelectric materials, thermistors, varistors, superconductors, printed circuit boards, electromagnetic shielding materials, optical dielectric materials, optical switches, photosensors, solar cells, optical wavelength converters, light absorption filters, temperature sensors, catalyst carriers, surface modifiers, sensor materials of e.g. gas sensors, surface protection agents, reflection-prevention agents, antimicrobial materials, and antifouling materials.    ADVANTAGE - The zinc oxide structure enables efficient and economical manufacture of zinc oxide particles.    DETAILED DESCRIPTION - A zinc oxide structure comprises zinc oxide crystal deposited in the crystal plane of a substrate by immersing the substrate having crystal plane comprising metal-containing material in a reaction solution such that the crystal plane which includes the metal-containing material which has a regular crystal-orientation structure in a fixed direction perpendicular to the c-axial direction, becomes downward. The crystal plane is formed from single-crystal material and/or epitaxial crystal material. The crystal plane of the zinc oxide structure is same as the surface orientation of the substrate. The zinc oxide structure has a zinc oxide crystal having an aspect ratio of one or more and a bottom radius of 250-450 nm, on the substrate. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of zinc oxide particles, which involves separating the zinc oxide structure from substrate; and    (2) zinc oxide particles having an aspect ratio of greater than 1.
