Light induced nucleation of metallic nanoparticles with frequency controlled shapes

We predict nucleation of pancake shaped metallic nuclei having plasmonic frequencies in resonance with a circularly polarized light. The same field can trigger nucleation of needle shaped metallic particles randomly oriented in the plane of polarization. Because the probabilities of these shapes are...

Zusammenfassung:We predict nucleation of pancake shaped metallic nuclei having plasmonic frequencies in resonance with a circularly polarized light. The same field can trigger nucleation of needle shaped metallic particles randomly oriented in the plane of polarization. Because the probabilities of these shapes are frequency dependent, our results pave a way to nucleation of nanoparticles of desired shapes.
