Abstract: In onder to solve the problem, such as expensive reagent and harsh synthesis conditions in the process of synthetize nano selenide mercury (nano-HgSe), we have successfully prepared oleic acid modified colloidal nano HgSe using common reagent by organometallic synthesis，and the results of X-ray diffractionanalysis(XRD) confirmed that the HgSe nanoparticles was a pure cubic structure; The results of transimission electronic microscopy showed that the particle size of the product was about 7 nm and dispersion was good. The UV-Vis-IR absorption spectrum showed that the product had strong absorption at 2 900 nm. In addition, the effect of tri-n-octylphosphine (TOP) on the yield of nano-HgSecombined with literature was researched, and the reaction mechanism of nano-HgSe synthesis was discussed in detail.
