我们报道了一种制备高度单分散的碲化铜纳米立方体、纳米片和纳米棒的方法。该程序是基于铜盐与碲化三辛基膦在双（三甲基甲硅烷基）氨基锂和油胺存在下的反应。CuTe纳米晶体显示出与局部表面等离子体共振相关的强近红外光吸收。我们利用这种等离子体共振的表面增强拉曼散射传感器的非常规光学探针的设计。此外，我们还在这里报告我们的初步分析使用碲化铜纳米晶体作为细胞毒性和光热剂。
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.
