ENHANCED RAMAN-SCATTERINGA physical interpretation is given for the experimentally observed substantial lowering of the lasing thresholds and the blue shift of the peak of the stimulated emission spectrum of a solution of the laser dye rhodamine 6G (R6G) with agglomerated silver nanoparticles. Results...
When R6G molecules are adsorbed onto the ERGO, the G peak clearly up-shifts and exhibits a frequency shift of ~14 cm−1. The observed Raman bands are assigned to the R6G molecules. The Fermi energy from the doping carrier concentration is obtained from the experiential formula13: ∆...
infrared and raman spectraIn terms of chemical enhancement in Surface Enhanced Raman Scattering (SERS), we investigated the effect of halide and other anions to rhodamine 6G (R6G) adsorbed Ag particles that were immobilized on the substrates. The residual species on chemically prepared Ag particles...
surface-enhanced raman scattering (SERS)silicon nanoporous pillar array (Si-NPA)Ag/Si-NPArhodamine 6G (R6G)A series of silver/silicon nanoporous pillar arrays (Ag/Si-NPAs) were prepared by an immersion-plating method through controlling the immersing times and their surface-enhanced Raman ...
RAMAN-SCATTERINGMONOLAYERBULKPressure-induced surface-enhanced Raman spectroscopy (PI-SERS) has garnered significant attention as a subfield of SERS detection due to its capacity to regulate the band gap between molecules and substrates through pressure modulation. Currently, SERS detection primarily ...
