Raman spectroscopy of optical phonon confinement in nanostructured materials
TL;DR: In this paper, a review of the results on the Raman spectroscopic investigations of optical phonon confinement in nanocrystalline semiconductor and ceramic/dielectric materials, including those in selenium, cadmium sulphide, zinc oxide, thorium oxide, and nano-diamond, is presented.
Journal ArticleDOI
Covalently attached graphene–ionic liquid hybrid nanomaterials: synthesis, characterization and tribological application
Rashi Gusain,Harshal P. Mungse,Niranjan Kumar,T. R. Ravindran,Ramanathaswamy Pandian,Hiroyuki Sugimura,Om P. Khatri +6 more
TL;DR: In this article, three variable Gr-IL hybrid nanomaterials, containing bis(salicylato)borate (BScB), oleate (OL), and hexafluorophosphate (PF6) anions, are synthesized to control their surface properties.
Journal ArticleDOI
High Pressure Behavior of ZrW 2 O 8 : Grüneisen Parameter and Thermal Properties
TL;DR: High pressure Raman spectroscopic studies are carried out on negative thermal expansion material ZrW2O8 and show that modes of energies much higher than 10 meV also contribute substantially to thenegative thermal expansion.
Journal ArticleDOI
Gold nanorods with finely tunable longitudinal surface plasmon resonance as SERS substrates
TL;DR: The synthesis of Au nanorods via a seed mediated approach and the influence of silver ions on the aspect ratio of the Au Nanorods are reported on.
Journal ArticleDOI
