Abstract:

The pervasiveness of nanoparticles and nanomaterials is rapidly expanding, and determination of their chemical composition can be achieved by Laser-Induced Breakdown Spectroscopy (LIBS) excited through an optical fiber of nanometer dimensions. We propose to develop a LIBS system for nanomaterials based upon recently demonstrated nanometer silica wires [Nature, Dec 2003] for excitation and an ultrasensitive avalanche photodiode (APD) array for optical detection. Moreover, we propose to employ a near-field approach to excite LIBS using femtosecond laser pulses, which yield sharper LIBS spectra and minimize damage to the nanofiber. The Phase-I goal is to demonstrate nanometer spatial resolution of compositional analysis of nanoparticles on surfaces. The ultimate goal is a system that will achieve single-pulse compositional analyses of nanostructure in various configurations, including for surface microscopy and in-situ monitoring of size and composition of nanoparticles in flowing reactant streams.
