Aerobic Synthesis of Cu Nanoplates with Intense Plasmon Resonances

Single-crystalline Cu nanoplates with a prominent in-plane dipole surface plasmon band are fabricated through reduction of copper salt with hydrazine using PVP as stabilizer and no need for inert atmosphere. Due to the lower free-electron character of copper, the interband transitions overlap, and therefore damp, the out-of-plane dipole plasmon resonance (see image).
