摘要 利用高温硫化法制备了高纯度MoS2纳米片。采用X射线衍射仪(XRD)、拉曼光谱仪(Raman spectrometer)、扫描电镜(SEM)和能谱仪(EDS)对MoS2纳米片的物相、结晶质量以及形貌进行了表征,分析了反应温度对MoS2纳米片的影响,并对MoS2纳米片的光敏性和气敏特性进行了研究。结果表明,MoS2纳米片对绿光响应度更高,红光次之,对甲醇和乙醇两种气体均有较高的灵敏度和响应/恢复速率,并对其气敏机理进行了讨论。

Abstract: High-purity MoS2 nanosheets have been synthesized by thermal sulfuration method. The phase and morphology of the samples were characterized by X-ray diffraction, Raman spectrometer, scanning electron microscope and energy dispersive spectrometer. The effect of reaction temperature on the MoS2 nanosheets was analyzed. The photo sensitive and gas sensitive properties of MoS2 were studied. It was found that the nanosheets was more sensitive to the green light than the red light. High sensor response and fast response/recovery time to methanol, ethanol were observed in MoS2 nanosheets based device, and its gas sensing mechanism was discussed.
Key words:  molybdenum disulfide    nanosheets    photo sensitive    gas sensitive
