Nanoparticle
synthesis by gas phase processes is a frontier area of applied science (1 nanometer = 10-9
meters = 10-3 micrometers). Materials composed of nanoparticles may have
special optical properties. For example silicon nanocrystals under optical excitation show
increases in luminescence yields of many orders of magnitude compared with bulk silicon.
Compact materials made of nanoparticles may exhibit ductile behavior and this has
stimulated efforts to fabricate ductile ceramic materials. Very small particles can also
be formed into large agglomerate structures whose properties resemble those of aerogels.
Our Laboratory has developed methods of synthesizing nanoparticles using a variety of
particle generators including laminar and turbulent flow chemical reactors, and laser
ablation. The new field of aerosol reactor design with applications to industrial
manufacture of powdered materials and optical fibers is based to a great extent on UCLA
research activities.
