摘　　要：为了解决合成纳米HgSe的工艺存在的试剂昂贵、合成条件苛刻等问题,采用有机金属合成法,利用常规试剂,成功制备出油酸修饰的纳米HgSe。X射线衍射分析结果证实纳米HgSe为纯相的立方结构;透射电镜结果显示,产物粒径为7 nm左右且分散性良好;紫外-可见-红外吸收光谱测试产物在2900 nm处存在强的吸收。结合文献考察三正辛基膦(TOP)对纳米HgSe产量的影响,详细探讨纳米HgSe合成的反应机理。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 about7 nm and dispersion was good.The UV-Vis-IR absorption spectrum showed that the product had strong absorption at 2900 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.
