Thermal evaporation growth and the luminescence property of TiO2 nanowires

A Modified Thermal Treatment Method for the Up-Scalable Synthesis of Size-Controlled Nanocrystalline Titania

“…Various methods have been previously reported on the synthesis of TiO 2 nanoparticles with improved chemical and physical properties, such as the hydrothermal and one-step dynamic hydrothermal process [17,18], chemical vapor deposition (CVD) [19], physical vapor deposition (PVD) [20], electrode deposition [21], plasma-assisted synthesis [22], microwave [23], micelle and inverse micelle [24], and the sol-gel method [25]. However, most of these methods are difficult to employ in large-scale production due to the complicated procedures involved, long reaction times, high reaction temperatures, and the involvement of toxic reagents and by-products in these synthesis methods.…”

Metal Oxide Nanowires – Structural and Mechanical Properties

“…Research interests in metal oxide nanowires commenced in 1990s. Up to now, there have been a considerable number of reports on success in the synthesis of 1-dimensional nanocrystalline structured nanowires of various metal oxides, such as CuO (Wang, Zhan et al 2001;Jiang, Herricks et al 2002), MgO (Ma and Bando 2003), ZnO (Tian, Voigt et al 2003;Vayssieres 2003;Heo, Norton et al 2004;Wang, Song et al 2007;Manoharan, Desai et al 2008), TiO 2 (Lakshmi, Partissi et al 1997;Li and Wang 1999;Li and Xia 2003;Wu, Shih et al 2005;Wu, Shih et al 2006), Al 2 O 3 (Valcarcel, Souto et al 1998;Xiao, Han et al 2002), Ga 2 O 3 (Wu, Song et al 2000), In 2 O 3 (Li, Zhang et al 2003), SnO 2 (Dai, Pan et al 2001), Sb 2 O 5 (Guo, Wu et al 2000), V 2 O 5 (Chen, Sun et al 2002), BaTiO 3 (Urban, Spanier et al 2003), etc. The methodology of synthesis is now well developed.…”

“…The methodology of synthesis is now well developed. Reported techniques include vapor-solid phase technique (Valcarcel, Souto et al 1998;Wu, Song et al 2000;Jiang, Herricks et al 2002;Ma and Bando 2003;Wu, Shih et al 2005;Wu, Shih et al 2006), chemical solution deposition (sol-gel) (Lakshmi, Partissi et al 1997;Urban, Spanier et al 2003), template etching (Xiao, Han et al 2002), percipitation (Tian, Voigt et al 2003;Vayssieres 2003), micro-emulsion (Guo, Wu et al 2000), flux growth (Dai, Pan et al 2001) and others. These are well reviewed by Shangkar et al (Shankar and Raychaudhuri 2005).…”

Large-Scale Synthesis of Semiconductor Nanowires by Thermal Plasma

“…In general, the design of 1D nanostructure emphasizes to strength the growth of crystal along one direction and restrict other two dimensions to nanosize. In recent years, considerable achievements have been made on preparation of 1D nanostructures and different synthetic strategies have been developed to fabricate various 1D nanostructures, including element (Nikoobakht & El-Sayed, 2003;Lu et al, 2005;Vivekchand et al, 2004;Wirtz & Martin, 2003), oxide (Dai et al, 2003;Ohgi et al, 2005;Wu et al, 2005;Zheng et al, 2002), nitride (Kim et al, 2002;Toury et al, 2003), sulfide (Gao et al, 2005;Kar & Chaudhuri, 2005;Zhu et al, 2003), and others (Hornbostel et al, 1995;Jun et al, 2006;X.Y. Wang et al, 2002), which makes it possible to further investigate their properties and applications in nanodevices.…”
