摘要

在高温高压下合成了二硫化钼（MoS2）的菱面体（R3）相。通过x射线全剖面衍射分析确定了合成粉末的晶体结构和晶格常数。扫描电镜结合能量色散x射线微分析证实了层状晶体的形成，元素组成Mo和S的比例为1:2。转移到SiO2/Si衬底上的3R-MoS2双分子层的发光光谱显示出低缺陷材料的窄发射线特征。

Optical and Structural Properties of 3R-MoS2 Synthesized at High Pressure

The rhombohedral (R3) phase of molybdenum disulfide (MoS₂) is synthesized from elemental components at high temperatures and pressures. The crystal structure and lattice constants are determined by full-profile X-ray diffraction analysis of the synthesized powder. Scanning electron microscopy in combination with energy-dispersive X-ray microanalysis confirms the formation of layered crystals with the elemental composition of Mo and S in the ratio of 1 : 2. Luminescence spectra of the 3R-MoS₂ bilayer transferred onto a SiO₂/Si substrate demonstrate narrow emission lines characteristic of low-defect materials.
