Significant metal-enhanced fluorescence due to a single Medusa-nanoparticle prepared by pulsed laser ablation in supercritical fluid

摘要

We developed a unique method for generating nanomaterials, by taking advantage of pulsed laser ablation (PLA) in both the gas and liquid phases. That is, PLA was performed in a supercritical fluid. This method enabled us to obtain the RGB light-emitting Si-nanocrystal and a white-light-continuum of Si nanocrystal ranging from near-UV to red wavelength regions.
