Abstract

Core-shell nanoparticles based on Au or Ag nanoshell core and cadmium sulfide semiconductor shell with differents size have been simulated using Mie and Drude approach. The results show that gold nanosphere coated by cadmium sulphide results has a maximum wavelength at 530 nm. This plasmon peak correspond to a ratio equal of 1.66. The optimised nanoshell allow light absorption in the visible region before cadmium sulfide coating. Thus, theses materials Au/CdS especially are good candidates for the design of functional nanocomposites used for photocatalytic application due mainly to its good light transparency.
