Resonantly enhanced Raman scattering and high-order Raman spectra of single-walled carbon nanotubes
The Raman spectra of single-walled carbon nanotubes (SWNTs) produced by the catalytic decomposition of hydrocarbons have been measured in the range of 100–7500 cm – 1. The tangential C–...

Waveguide luminescence and Raman spectroscopy: Characterization of an inhomogeneous film at different depths
In graded-index planar optical waveguides, different guided modes propagate in layers with different thickness. By comparison of spectra (Raman, luminescence) taken by waveguide excitation in differen...

We have synthesized specimens of nanometric lead dispersion in a glassy Al–Cu–V matrix by rapid solidification of the corresponding melt. The microstructure has been designed to avoid superconducting percolation due to coupling of the neighboring particles by the proximity effect. Using these specimens, we have determined quantitatively the effect of size of the ultrafine lead particles on the superconducting transition. ©1999 American Institute of Physics.
