A facile one-pot method was utilized at room-temperature for the synthesis of novel ternary nanocomposite of Ag@RGO/ZnO, which is introduced as a low cost, efficient and reliable UV absorber. The crystalline, morphological, structural, and optical characteristics of the as-synthesized samples were investigated by various techniques such as XRD, FE-SEM, HR-TEM, XPS, and DRS. The measurements confirm the successful fabrication of the Ag@RGO/ZnO ternary nanocomposite. Optical characterization showed the synergetic role of Ag NPs and RGO NSs in the enhancement of the light absorption of the ternary nanocomposite in the UV portion compared to the bare ZnO NPs. Additionally, band-gap narrowing was observed due to the Ag-doping impact where potential applications for the proposed nanocomposite have been suggested.
在室温下采用一种简便的一锅法合成了新型Ag@RGO/ZnO三元纳米复合材料，该材料被用作低成本、高效且可靠的紫外线吸收剂。通过XRD、FE-SEM、HR-TEM、XPS和DRS等多种技术对合成样品的晶体、形态、结构和光学特性进行了研究。测量结果证实了Ag@RGO/ZnO三元纳米复合材料的成功制备。光学表征表明，与裸ZnO纳米颗粒相比，Ag纳米颗粒和RGO纳米片在增强三元纳米复合材料在紫外区域的光吸收方面具有协同作用。此外，由于Ag掺杂的影响，观察到带隙变窄，并提出了该纳米复合材料的潜在应用。
