Journal ArticleDOI
A Guide to and Review of the Use of Multiwavelength Raman Spectroscopy for Characterizing Defective Aromatic Carbon Solids: from Graphene to Amorphous Carbons
TL;DR: In this paper, the authors reviewed the use of Raman spectroscopy in the characterization of sp2 hybridized carbon samples containing defects and discussed the possible influence of both phonon confinement and curvature of aromatic planes on the shape of the Raman spectrum.
Journal ArticleDOI
Resonant Raman spectroscopy of single-wall carbon nanotubes under pressure
Alexandre Merlen,Nedjma Bendiab,Pierre Toulemonde,A. Aouizerat,A. San Miguel,J.L. Sauvajol,Gilles Montagnac,H. Cardon,Pierre Petit +8 more
TL;DR: In this paper, the authors performed high pressure resonant Raman experiments on single-wall carbon nanotubes with argon as pressure transmitting medium and found no clear sign of phase transformation up to the highest studied pressure.
Journal ArticleDOI
Optical Properties of Silver and Gold Tetrahedral Nanopyramid Arrays Prepared by Nanosphere Lithography
Mohammadali Tabatabaei,Alexandre Sangar,Nastaran Kazemi-Zanjani,Philippe Torchio,Alexandre Merlen,François Lagugné-Labarthet +5 more
TL;DR: In this paper, a tetrahedral nanopyramids made of silver and gold over ITO/glass surfaces are fabricated using nanosphere lithography (NSL) with the deposition of thicker metal layers.
Journal ArticleDOI
Surface enhanced Raman spectroscopy of organic molecules deposited on gold sputtered substrates
Alexandre Merlen,V Gadenne,V Gadenne,Julien Romann,Virginie Chevallier,L. Patrone,L. Patrone,J.-C. Valmalette +7 more
TL;DR: It is demonstrated that it is possible to control the surface plasmon band absorption in SERS experiments performed with methylene blue, zinc octacarboxyphthalocyanine, 4-aminothiophenol and cysteamine, and a strong influence of the nature of the adsorbed molecule on the enhancement factor for a given wavelength is noticed.
Journal ArticleDOI
High-pressure behavior of polyiodides confined into single-walled carbon nanotubes: A Raman study
Laurent Alvarez,J.-L. Bantignies,R. Le Parc,R. Aznar,J.L. Sauvajol,Alexandre Merlen,Denis Machon,A. San Miguel +7 more
TL;DR: The high pressure behavior of polyiodides confined into the hollow core of single-walled carbon nanotubes organized into bundles has been studied by means of Raman spectroscopy as mentioned in this paper.
