Abstract
- PbS-Au heterodimer with Au nanoparticles grown on the tips of PbS nanooctahedrons has been successfully fabricated in ethylene glycol by a facile one-pot method. The morphology of the heterodimers could be changed by the displacement of the capping agent. The products were characterised by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive spectrometer analysis and UV-vis absorption spectra. Compared with traditional synthesis methods of the heterodimers, the one-pot process is facile for large-scale synthesis. Owing to the charge transition between the heterointerface, a broad absorption peak around 372 nm is observed in UV-vis absorption spectra. [ABSTRACT FROM AUTHOR]
