Quantum confinement of lead titanate nanocrystals by wet chemical method

• Single crystalline NSs of PbTiO3 fabricated by wet chemical method.
• PbTiO3 NSs were uniform and continuous along the long axis.
• Tetragonal perovskite structure with the diameter 20 nm and length 3 μm.
• XPS spectrum was fitted with Lorentzian function respectively.
• The size of the images is also 10 μm × 10 μm.

Lead Titanate (PbTiO3) is a category of the practical semiconductor metal oxides, which is widely applied in various scientific and industrial fields because of its catalytic, optical, and electrical properties. PbTiO3 nanocrystalline materials have attracted a wide attention due to their unique properties. PbTiO3 nanocrystals were investigated by X-ray diffraction (XRD) to identify the PbTiO3 nanocrystals were composed a tetragonal structure. The diameter of a single sphere was around 20 nm and the diameter reached up to 3 μm. The chemical composition of the samples and the valence states of elements were determined by X-ray photoelectron spectroscopy (XPS) in detail.
