The designer optical resonances of metal nanoshells
Metal nanoshells consist of a dielectric or semiconducting core coated with a metallic layer of nanometer scale dimensions. Gold nanoshells with silica cores were fabricated by first attaching gold colloid to the surface ...
Fullerene triplet states in solution
Triplet state pre-equilibration by reversible energy transfer has been observed by transient-absorption spectroscopy in mixed toluene solutions of C70 and C60 and of C70 and C60(CH 3)2. The equilibrium constants governing ...
Nanoparticle assemblies and interactions
Silica nanoparticles coated with functionalized organosilane molecules are used as substrates for the formation of assemblies of gold nanoparticles. In an assembly of nanoparticles, the optical response of each nanoparticle ...
