采用不同的方法对简并掺杂的硫系铜纳米粒子(Cu2−xSe白沸石和Cu1.1S covelite)的局部表面等离子体共振(LSPRs)进行了修饰。Ag(I)和Cu(I)的阳离子交换(Cu2−xSe)和插层(Cu1.1S)的比较表明,Ag(I)引起LSPR的不可逆的空气稳定位移。这与Cu1.1S - au2s混合纳米片形成时Au(I)阳离子交换到Cu1.1S纳米片的影响进行了比较。此外,我们还展示了Cu2−xSe上Au畴的生长,并讨论了获得的双等离子体Cu2−xSe - Au杂化粒子中两个等离子体部分的相互作用。
Localized surface plasmon resonances (LSPRs) of degenerately doped copper chalcogenide nanoparticles (NPs) (Cu2−xSe berzelianite and Cu1.1S covellite) have been modified applying different methods. The comparison of the cation exchange (Cu2−xSe) and intercalation (Cu1.1S) of Ag(I) and Cu(I) has shown that Ag(I) causes a non reversible, air stable shift of the LSPR. This was compared to the influence of Au(I) cation exchange into Cu1.1S platelets under the formation of Cu1.1S–Au2S mixed nanoplatelets. Furthermore, we show the growth of Au domains on Cu2−xSe, and discuss the interaction of the two plasmonic parts of the obtained dual plasmonic Cu2−xSe–Au hybrid particles.
