Embodiment Construction

[0024] In this embodiment, the precursor adopts analytically pure hydrated zinc acetate [Zn(CH 3 COO) 2 2H 2 O], which is implemented in the following way:

[0025] Step 1, analyze pure zinc acetate hydrate [Zn(CH 3 COO) 2 2H 2 O], placed in a vacuum oven, dried in vacuum at 85°C for 24 hours, and then taken out for use;

[0026] Step 2, adding the dried zinc acetate into deionized water to form a solution with a concentration of 0.3-0.5M;

[0027] Step 3. Add the prepared solution into the lined polytetrafluoroethylene container so that the added solution accounts for 25% of the volume of the lined polytetrafluoroethylene container, and put the pre-cleaned substrate into the lined polytetrafluoroethylene container In solutions in vinyl containers, the polished side of the substrate is up (except glass substrates);

[0028] Step 4. Place the PTFE-lined container in a metal reactor. The metal reactor should be able to withstand the reaction pressure and temperature of 1....

Abstract

The invention provides a C-axle preferred orientation single-crystal ZnO hexagonus microtube preparation method. C-axle preferred orientation single-crystal ZnO hexagonus microtube is prepared from predecessor through hydrothermal synthesis, the said predecessor being zinc salt or zincate, including zinc acetate or zinc acetate group chemical etc. ZnO microtube prepared in the invention is single crystal microtube, and has identical complete hexagonus structure with crystal structure of hexagonal faserblende which is ZnO single crystal, C-axle of which is axially oriented along the tube. Hydrothermal synthesis method in the invention has advantages of simple process, good product uniformity and repeatability ,predecessor being easily synthesized.

Description

technical field [0001] The invention belongs to the field of low-dimensional structure semiconductor optoelectronic materials, and particularly relates to a method for obtaining C-axis preferred orientation single crystal ZnO hexagonal micropipes. Background technique [0002] Since Lijima, a Japanese electron microscope expert, first discovered carbon nanotubes in 1991, carbon nanotubes have become one of the research hotspots worldwide because of their unique mechanical, electrical and chemical properties. In carbon nanotubes, due to the quantum confinement effect of electrons, electrons can only move along the axial direction of the nanotube in the single-layer graphite sheet, and their radial movement is restricted, so that carbon nanotubes have unique electrical properties, thermal conductivity and unique mechanical properties. Inspired by carbon nanotubes, international material, physical and chemical scientists have broadened the idea of ​​nanotubes to the field of s...
