Abstract :
Matrices of titania nanotubes (TiO2NTs) have been prepared by anodization of Ti foils in ethylene glycol based electrolyte. These matrices were subjected to annealing at various temperatures or exposed to a focused laser beam and were characterized by transmission electron microscopy (TEM), micro-cathodoluminescence (CL) and Raman scattering (RS) spectroscopy. The obtained data demonstrate possibilities to control the crystallographic structure of TiO2NTs by means of focused laser beam writing. These findings open novel prospects for the design and fabrication of titania nanotube structures.
