We have successfully fabricated hybridized nanoparticles composed of polydiacetylene nanocrystal (core) and Ag or Pt nanoparticle (shell) by means of visible-light-driven photocatalytic reduction. Difference in the reduction mechanism between Ag and Pt affected the size of deposited metal-nanoparticlcs. Next, the Ag-nanoparticles preformed on the polydicetylene nanocrystals were employed as both a catalyst and a substrate for an electroless plating. As a result, we succeeded in the fabrication of thicker Pt-shell and bimetal shell (Ag-Au, Ag-Pt, Ag-Pd). The core-shell-type nanoparticles were characterized using SEM, TEM, powder-XRD, EPMA and UV-Vis-NIR extinction spectroscopy.
