Raman spectroscopy of iodine-doped double-walled carbon nanotubes [PDF]

open access: yes, 2004
We present a Raman spectroscopy study of iodine-intercalated (p-type-doped) double-walled carbon nanotubes. Double-walled carbon nanotubes (DWCNTs) are synthesized by catalytic chemical vapor deposition and characterized by Raman spectroscopy.

Silicon-nitride waveguides for on-chip Raman spectroscopy [PDF]

open access: yes, 2014
The evanescent tail of the guided modes can efficiently excite Raman active molecules located in the cladding of a waveguide. Similarly, a significant fraction of the total emitted Stokes power is evanescently coupled to the same mode.

A new Raman technique of superior spectral resolution [PDF]

open access: yes, 1982
Raman-active vibrational modes are coherently excited by the transient stimulated Raman process. A subsequent delayed probe of relatively long duration interacts with the freely relaxing vibrations.

Raman spectroscopic study of the mineral xonotlite Ca6Si6O17(OH)2 - A component of plaster boards [PDF]

open access: yes, 2012
The mineral xonotlite Ca 6Si 6O 17(OH) 2 is a crystalline calcium silicate hydrate which is widely used in plaster boards and in many industrial applications. The structure of xonotlite is best described as having a dreierdoppelketten silicate structure,

Lab-on-a-chip Raman sensors outperforming Raman microscopes [PDF]

open access: yes, 2016
We demonstrate that the signal-to-noise ratio and signal collection efficiency in evanescent waveguide-based Raman spectroscopy exceeds that in Raman microscopes.
