Abstract: 
Copper chalcogenides are the focus of research due to their abundant elements and their low toxicity. In particular, plasmonic Cu2-xSe and Cu1.1S NPs represent a main topic of recent research efforts due to the postsynthetic tunability of their localized surface plasmon resonance (LSPR). In this paper, we describe the growth of Cu2-xSe-CuPt and Cu1.1S-Pt hybrid nanoparticles. In both systems we investigate the quenching of the LSPR in relation to the Pt ratios. The resulting Cu2-xSe-CuPt hybrid parades form a cubic CuPt domain during the growth process. On the Cu1.1S platelets, several, 2-3 nm sized Pt domains are formed. The changes for both systems finally result in a nearly complete damping of the LSPRs. The structural changes of the chalcogenide domain as well as of the metal domain are analyzed in depth and are related to the changes in the LSPRs of the hybrid systems.
