摘要: 选择一种高活性模板剂通过简单的诱导组装工艺, 合成了结构均一有序的硫化汞一维纳米组装链, 该纳米链由直径约为30 nm的粒子组装而成, 长度约0.6-1.0 μm. 通过XRD、TEM、FT-IR、UV-Vis光谱等手段对产物结构进行了表征. UV-Vis实验结果发现, 产物具有良好的紫外吸收性能. 产物对荧光素具有灵敏的荧光猝灭效应, 预计在微观修饰、纳米器件、样品检测等领域具有潜在的应用价值. 同时还对产物的形成机理做了初步探讨.

Abstract: Assembly nanoparticle HgS chains with good optical properties were synthesized with high activity polyacrylamide as the template. These high-quality HgS nanoparticle chains showed well-defined nanoscale structures and regular morphology. The nanoparticle chains were 0.6-1.0 μm in length and the nanoparticles were about 30 nm in diameter. Product structures were studied by XRD, TEM and FT-IR. Products had good optical properties for UV-Vis absorption and fluorescence quenching. The products have potential applications in many fields such as micromodification, nanodevices and sample detection. The morphology formation mechanism for the HgS nanoparticle chains was also investigated.

Key words: HgS, Nanoparticle chains, Assembly, Optical property
