[0026] (1) Pre-patterning of FTO conductive substrate

[0027] Set the surface area to 1 cm 2 The FTO conductive substrates were ultrasonically cleaned in acetone, absolute ethanol, and deionized water, each time for 150 s, and dried at room temperature after taking them out. Build a two-beam laser interference optical path system. The two-beam laser interference system is composed of a laser, beam splitting, and refraction. The laser emits a beam of laser light, which is divided into two coherent beams by the beam splitting system. Composed of a beam splitter, a half-wave plate and a polarizer, the two beams of coherent light are spatially symmetrical through the refraction system, so that they irradiate the sample at the same time at an incident angle of 3°, the exposure energy is 80mJ, and the exposure time is 1s. By changing the two-beam spatial light interference parameters, including spatial angle, incident angle, phase angle, polarization state, interference light inte...

Abstract

Belonging to the technical field of nano-material preparation, the invention relates to a preparation method of a directionally growing titanium dioxide nano-cluster array. The method is characterized by being realized through the following technical scheme of: utilizing a dual-beam or multiple-beam laser interference optical path system to perform laser interference lithography etching on a cleaned FTO conductive substrate, putting the pre-patterned FTO conductive substrate into a solution composed of deionized water, tetrabutyl titanate and concentrated sulfuric acid for hydrothermal reaction, and conducting heating by a constant temperature drying box to prepare the directionally growing titanium dioxide nano-cluster array. Through change of the parameters of laser interference lithography, the growth cycle of the titanium dioxide nano-cluster array can be adjustable from the nanoscale to the micron scale, and the diameter and length of titanium dioxide nanowires can be adjusted by changing the hydrothermal process heating time and heating temperature.

Description

technical field [0001] The invention relates to a preparation method of an oriented growth titanium dioxide nano-cluster array, which belongs to the field of nano-material processing. Background technique [0002] In the 20th century, the new discipline of nanotechnology was born. Nanoscience and technology is an interdisciplinary subject that studies the laws and characteristics of the movement of molecules, atoms and electrons at the nanoscale. The ultimate goal of human research and development is to explore the microscopic world. And directly manipulate or control individual atoms according to their own needs. Nanotechnology has been widely concerned by scientists since it was proposed, and has developed rapidly in just a few decades. As a branch of nanotechnology, nanomaterials has become a frontier and hotspot of scientific research because of its theoretical significance and great potential in application, among which nanoscale TiO 2 Due to its special physical and ...
