Abstract

Optical properties of silicon and indium phosphide nanoparticles with emission throughout the visible wavelength range are presented. The peak emission wavelength of these nanoparticles is controlled by the reaction time and by post-growth etching treatments. Ultrafast spectroscopy is used to determine the photoluminescence lifetime in order to correlate the spectral response with the structural and chemical characterization of these nanoparticles. The measured lifetimes are used to identify surfactant, surface, and core nanoparticle emission. The nanoparticles exhibit efficient emission that is quenched when embedded within particular polymeric matrices.
