Abstract
|
|
|---|---|
| In this presentation we show how to achieve an extreme control over the energy deposited in plasmonic systems with femtosecond laser pulses to induce predictable changes in temperature and in turn, in the morphology of gold nanoparticles. We demonstrate that there exists a laser fluence window that combined with the appropriate concentration of the organic surfactant hexadecyltrimethylammonium (CTAB) leads to a gentle multishot modification of the nanorods to a stable situation at which the nanorod aspect ratio is the same for all the nanorods. The result is an ensemble of optically identical nanorods with unprecedented properties. PRESENTACION ORAL. | |
