Hydrothermal synthesis and photoluminescence of TiO2 nanowires

Abstract Anatase TiO 2 single crystalline nanowires have been successfully synthesized using a simple hydrothermal synthesis method from TiO 2 nanoparticles. X-ray diffraction, transmission electron microscopy and high-resolution electron microscopy investigations show the TiO 2 nanowires have high crystallinity with diameter range from 30 to 45 nm and length in several micrometers. The TiO 2 nanowires can emit blue–green light peaked at 487 nm under excitation at 413 nm.
