Fabrication of TiO2 nanowire arrays using laser interference lithography aided hydrothermal method

Abstract

Titanium dioxide (TÍO2) is one of the most widely investigated semiconductor materials because of its unique properties. TiO2 nanowire arrays can be synthesized through a two-step method, the fluorine-doped tin oxide (FTO) substrates were ablated using laser interference lithography technology, and TiO2 nanowire arrays grown on the patterned FTO substrates. The TiO2 nanowire arrays were characterized by SEM and XRD measurements. This work provides a high efficient method for the fabrication of ordered TiO2 nanowire arrays for different applications in highly functionalized assemblies and composites.
