title: Self-assembly synthesis of single-crystalline tin oxide nanostructures by a poly(acrylic acid)-assisted solvothermal process.
abstract: Single-crystalline SnO(2) nanocones with an average 1.0 mum in length and 100-500 nm in root size and their self-assembly morphologies were obtained through a solvothermal process in the presence of poly(acrylic acid). X-ray diffraction, electron microscopy, Raman scattering spectra, and infrared (IR) spectra were used to characterize the nanocones. The as-synthesized SnO(2) nanocones with the typical rutile phase exhibit preferential growth along the [001] direction and high chemical stability. The proposed mechanism for the formation of SnO(2) nanocones and the further self-assembly into hollow sphere-like superstructure is discussed.
