Graphene oxide is well known for its adsorption properties with aromatic compounds. In this study, graphene oxide and eco-friendly ternary CuInS/ZnS QDs were used to prepare graphene oxide-qunatum dots (GO-QDs) nanocomposite via in-situ method. The composite was characterized using ultraviolet-visible (UV-Vis) spectroscopy, photoluminescence (PL) spectroscopy, transmission electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscopy. The effect of the polycyclic aromatic hydrocarbons (PAHs) on the PL properties of the nanocomposite was investigated. The results showed that the addition of PAHs increased the PL intensity of the nanocomposite. This "turn-on" fluorescence approach can be used for the successful detection of PAHs in aqueous media.
氧化石墨烯因其对芳香族化合物的吸附特性而闻名。在本研究中，氧化石墨烯和环保型三元CuInS/ZnS量子点通过原位法用于制备氧化石墨烯-量子点（GO-QDs）纳米复合材料。使用紫外可见（UV-Vis）光谱、光致发光（PL）光谱、透射电子显微镜（TEM）和傅里叶变换红外（FT-IR）光谱对该复合材料进行了表征。研究了多环芳烃（PAHs）对纳米复合材料PL性能的影响。结果表明，PAHs的加入增加了纳米复合材料的PL强度。这种“开启”荧光方法可用于在水性介质中成功检测PAHs。
