Abstract

The invention discloses a method for preparing a great amount of monocrystal zinc oxide nano rod arrays on glass by a low temperature solution method, which comprises the following steps: ultrasonically cleaning the surface of the glass by deionized water, acetone and anhydrous ethanol in order, dissolving soluble zinc salt and hexamethylenetetramine in proportion in a certain amount of deionized water; and placing the solution and treated glass substrate in an acid resistant and alkali resistant enclosed container, heating for 5-20 hours under the temperature of 50-70 DEG C. The method of the invention is capable preparing a great amount of monocrystal zinc oxide nano rod arrays on glass. According to the method of the invention, coating a seed crystal layer in advance is not required, adding lye for regulating the pH value is not required, the method is simple and is easy to be controlled, and the production cost is low.

Description

technical field [0001] The invention relates to a low-temperature solution method for preparing zinc oxide nanorod arrays, in particular to a method for preparing a large number of single-crystal zinc oxide nanorod arrays on glass. Background technique [0002] Zinc oxide is a semiconductor material with a wide bandgap of the II-VI group. The crystal structure is Wurtzite (Wurtzite) hexagonal crystal system, the bandgap width is 3.37eV, and it has high exciton binding energy (60meV) and Lower electron-induced defects. Therefore, ZnO has potential applications in nanoscale electronic and optoelectronic devices. Simple and efficient preparation of high-quality ZnO single crystals is very important for scientific research and technological progress. [0003] There are many reports on the preparation of zinc oxide micro-nanostructures by using soluble zinc salt and hexamethylenetetramine under the conditions of solution chemical growth method, but the reaction temperature of s...
