本工作通过高压固相复分解反应（HPSSM）合成块体Re₃N。利用X射线粉末衍射（XRD）、扫描电子显微镜（SEM）和能量色散X射线分析（EDS）对高压样品进行结构表征与元素成分确定，结果表明利用HPSSM法合成的Re₃N具有较高的晶体质量。在77 K到873 K温度范围内利用拉曼散射研究Re₃N的晶格振动特性。基于三（四）声子耦合模型，研究Re₃N拉曼声子模频率的红移和拉曼峰的宽化现象，结果表明高温条件下Re3N拉曼散射效应中三声子耦合过程占主导。高压同步辐射研究表明Re3N具有很高的体弹模量（B₀=417 GPa），是一种潜在的超硬材料。

Well-crystallized bulk of Re₃N was synthesized through a High-Pressure Solid-State Metathesis (HPSSM) reaction. The structural characterizations and compositions of as-prepared samples were determined by X-ray powder diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray analysis (EDS), which indicated high crystalline quality of Re₃N. The vibrational properties of Re₃N lattices were studied by the temperature dependence on Raman spectroscopy between 77 K and 873 K. With the temperature increasing, the red-shift and broadening of Raman bands of Re₃N could be well fitted using a model involving three- and four-phonon decay processes. Our fitting results indicated that the three-phonon decay processes were dominant over the four-phonon ones at high temperatures. The bulk modulus B0=417 GPa for Re₃N was determined by high-pressure synchrotron radiation research indicating that Re₃N synthesized through HPSSM reaction may be a potential superhard materials.
