- To expand the scope of plasmon-driven synthesis to new elements.
Main Methods:
- Seed-mediated growth of Cu nanostructures in aqueous solution.
- Synthesis conducted under an inert atmosphere with controlled pH and temperature.
- Investigation of surfactant (polyvinylpyrrolidone) concentration effects on nanostructure morphology.
Main Results:
- Successfully synthesized triangular and hexagonal Cu nanoprisms.
- Demonstrated that Cu nanostructure growth is dependent on surfactant concentration.
