A Facile Sonochemical Method for Synthesis of Mercury Selenide Nanostructures

Mercury selenide (HgSe) nanostructures has been achieved from N-N'-bis(salicylaldehyde)-1,2-phenylenediimino mercury [Hg(salophen)] as a new precursor. Cubic phase HgSe nanoparticles with the size of mostly 20-40 nm were produced by sonication of the Hg(salophen) precursor. The products were characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, photoluminescence, energy dispersive X-ray spectroscopy and Fourier transformed infrared spectroscopy. The results of this paper show that the shape and size of mercury selenide nanostructures can be controlled systematically by adjusting reaction parameters, such as the ultrasonic power, temperature, capping agent and reaction time.
