We demonstrate a new route for the synthesis of heterogeneous nanoparticles (NPs) composed of a gold domain (Au) and a heavily doped semiconductor domain (CuSe) which exhibit a broad localized surface plasmon resonance (LSPR) arising from interactions between two nanocrystal domains. We also demonstrate the in-vitro cytotoxicity and photo thermal efficiency of as prepared Au-CuSe heterodimer nanoparticles. This work establishes a new way of tuning LSPR by engineering the density of free charge carriers in two interacting domains.
我们展示了一种合成由金域（Au）和重掺杂半导体域（CuSe）组成的异质纳米颗粒（NPs）的新途径，这些纳米颗粒表现出由两个纳米晶域之间的相互作用产生的宽局域表面等离子体共振（LSPR）。我们还展示了所制备的Au-CuSe异二聚体纳米颗粒的体外细胞毒性和光热效率。这项工作通过设计两个相互作用域中自由电荷载流子的密度，建立了一种调节LSPR的新方法。
