摘　　要：Mercury telluride （HgTe） nanoplatelets were obtained via a facile solvothermal reaction of mercury（I） chloride and tellurium powder in ethylenediamine （en）. Mercury（I） was first applied as the mercury sources to prepare nanocrystal HgTe; moreover, the proposed mechanism for the fabrication of the sample was discussed in detail. The HgTe nanoplatelets were characterized by powder X-ray diffraction （PXRD）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, high-resolution transmission electron microscopy （HRTEM） and Fourier transform infrared spectroscopy （FT-IR）. The absence of IR absorption may render the title nanocrystal useful as an IR transparent material in the region.Mercury telluride （HgTe） nanoplatelets were obtained via a facile solvothermal reaction of mercury（I） chloride and tellurium powder in ethylenediamine （en）.
