Synthesis and characterization of single crystalline PbO nanorods via a facile hydrothermal method

Single crystalline β-PbO nanorods with diameter range from 40 to 120 nm and length up to 500 nm have been synthesized via a facile hydrothermal method in the presence of citrate. X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electro-microscope (HRTEM) and SAED were used to characterize the as-obtained samples. An interesting intermediate state of self-assembled β-PbO rod-like nanoparticles was found and the possible formation mechanism of single crystalline β-PbO nanorods was also discussed.
