We report a procedure to prepare highly monodisperse copper telluride nanocubes, nanoplates, and nanorods. The procedure is based on the reaction of a copper salt with trioctylphosphine telluride in the presence of lithium bis(trimethylsilyl)amide and oleylamine. CuTe nanocrystals display a strong near-infrared optical absorption associated with localized surface plasmon resonances. We exploit this plasmon resonance for the design of surface-enhanced Raman scattering sensors for unconventional optical probes. Furthermore, we also report here our preliminary analysis of the use of CuTe nanocrystals as cytotoxic and photothermal agents.
我们报告了一种制备高单分散性铜碲纳米立方体、纳米板和纳米棒的方法。该方法基于铜盐与三辛基膦碲在双(三甲基硅基)酰胺和油胺存在下的反应。CuTe 纳米晶体显示出与局域表面等离激元共振相关的强近红外光吸收。我们利用这种等离子体共振设计了用于非常规光学探针的表面增强拉曼散射传感器。此外，我们还在这里报告了我们对 CuTe 纳米晶体作为细胞毒性和光热剂的初步分析。
