Nanopatterning of metal nanoparticles can be used to energy conversion and storage applications, including polymer solar cells and lithium-ion batteries. Herein, we demonstrate that poly(styrene-b-2-vinylpyridine) block copolymer templates were used to make arrays of metal nanoparticles. We found that metal nanoparticles induced the surface plasmon resonance effect in the optoelectronic devices. Increased light absorption of the polymer thin layer with the incorporation of metallic nanostructures was demonstrated, resulting in higher efficiency compared to conventional optoelectronic devices. Moreover, metal patterned arrays were used as catalyst to growth silicon nanowires via vapor-liquid-solid process. Si/SiOx core-shell nanocoils were protruded out from the surface of bulk Si via high temperature annealing of metal nanoparticle-decorated Si powders. The carbon-coated urchin-like Si-based materials were tested in lithium-ion battery as anode materials. |
