Abstract
Fishbone-like PbMoO4 nanostructures are successfully obtained via the surfactant-assisted
hydrothermal method at 160 ?C. Polyethylene glycol (PEG2000) is used as the template agent. The
nanostructures are characterized via X-ray diffraction, field-emission scanning electron microscopy,
Fourier transform infrared spectroscopy, ultraviolet-visible light (UV-Vis) spectroscopy, and
photoluminescence (PL) measurements. The PbMoO4 morphology is highly associated with the molecular
nature of PEG2000. PbMoO4 nanoparticles obtained from PEG2000 have a fishbone-shaped, scheelite-type
tetragonal structure, in which numerous secondary branches vertically grow on both sides of the main
stem. The structures exhibit broad PL emission bands with the maximum at 306 and 390 nm when excited
at 250 nm. In addition, the UV-Vis absorption edge of the structures is in the 280 to 310 nm region,
and the band gap is 4.07 eV. A plausible formation mechanism for the fishbone-like PbMoO4
nanostructures is also discussed.
