Resumen
In this paper, the interface phonons in a core-shell quantum dot are theoretically studied by a resonant Raman scattering (RRS) process. Fröhlich electron–phonon interaction is considered in the framework of the dielectric continuum approach. The Raman peaks are found to be sensitive to the size of strongly confined shell. The shift of the Raman resonant peaks is a consequence of the change of observed dispersion of the phonon frequency. The Raman intensity changes in the system with shell thickness, originating from the competition between the spacial distribution of electron wave function and the number of phonons joining in the RRS process. The analysis of the Raman spectra gives a physical explanation to the size-selective nature of the Raman process and some experimental results.

Resumen
ABSTRACTThe effect of temperature (5K to 300K) on the Raman scattering due to A1g/A1’ modes associated with the out-of-plane vibrations in bilayer (2L) and trilayer (3L) MoTe2 is investigated. The temperature evolution of the modes critically depends on the flake thickness. The A1g mode intensity in 2L MoTe2 observed with λ=632.8 nm light excitation decreases with decreasing temperature down to 220K and the mode vanishes from the Stokes scattering spectrum in the temperature range between 160K and 220K. The peak recovers at lower temperatures and at T=5K it becomes three times more intense that at room temperature. Similar non-monotonic intensity evolution is observed for the A1’ mode in 3L MoTe2 in which tellurium atoms in all three layers vibrate in-phase. On the contrary, the intensity of the other out-of-plane Raman-active mode in which vibrations of tellurium atoms in the central layer of 3L MoTe2 are shifted by 180° with respect to vibrations in outer layers, only weakly depends on temperature.The observed quenching of the out-of-plane modes in the Raman scattering in thin MoTe2 layers is related to the destructive interference of the resonant- and the non-resonant contributions to the Raman scattering. The resonance with the M point of the Brillouin zone in few-layers of MoTe2 is considered. Effects related to the resonant quenching of the in-phase out-of-plane mode are discussed.

Resumen
The resonant Raman scattering of a quantum wire in a strong magnetic field is studied, focused on the effect of long range Coulomb interaction and the spin–charge separation. The energy–momentum dispersions of charge and spin excitation obtained from Raman cross-section show the characteristc cross-over behaviour induced by inter-edge Coulomb interaction. The "SPE" peak near resonance in polarized spectra becomes broad due to the momentum dependence of charge velocity. The broad peak in the depolarized spectra is shown to originate from the disparity between charge and spin excitation velocity.

Resumen
Raman vibrational bands are sensitive to fluctuations in the molecular environment. Variations in the bandwidth and peak position can then be utilized to monitor molecular forces and interactions present in condense phases. Nuclear Magnetic Resonance (NMR) provides a convenient probe for the study of molecular reorientation in liquids since nuclear spin relaxation times are dependent on the details of molecular motion. Presented here is the solvent study of the Raman bandwidths and frequency displacements of the mode of the compounds CH3MCI3 (M = C, Si, Ge, Sn) in a number of solvents of widely varying molecular structure. Also, a detailed isotope dilution study of the modes in CH2CI2/CD2CI2 mixtures is presented. In this set of experiments, I observed broadening of the v1 mode of CH2C12 upon dilution,which is the first experimental observation of such behavior. The temperature-dependent carbon-13 relaxation times and nuclear Overhauser enhancements in neat dichloromethane were measured. In this study we found that the molecular reorientation of this molecule was highly anisotropic, but could be well characterized assuming quasi-symmetric top behavior. In addition, in order to gain a more complete understanding of the reorientational dynamics in dichloromethane, we analyzed the 13-C NMR relaxation of CH2CI2 both in "inert" solvents of differing viscosities and in interactive solvents of varying Lewis basicities. Various theoretical models were also applied in order to characterize dichloromethane1s reorientational dynamics.

Resumen
This article examines the optical properties of single-wall carbon nanotubes (SWNTs) and nanographene. It begins with an overview of the shape of graphene and nanotubes, along wit the use of Raman spectroscopy to study the structure and exciton physics of SWNTs. It then considers the basic definition of a carbon nanotube and graphene, focusing on the crystal structure of graphene and the electronic structure of SWNTs, before describing the experimental setup for confocal resonance Raman spectroscopy. It also discusses the process of resonance Raman scattering, double-resonance Raman scattering, and the Raman signals of a SWNT as well as the dispersion behavior of second-order Raman modes, the doping effect on the Kohn anomaly of phonons, and the elastic scattering of electrons and photons. The article concludes with an analysis of excitons in SWNTs and outlines future directions for research.

Resumen
When nonlinear four-wave mixing (FWM) is resonant with a Raman transition, it causes coupling between lightwaves separated by two Raman frequency shifts. This coupling is manifested in effects such as Raman gain suppression, higher-order Stokes generation, and coherent Raman spectroscopies (e.g., CARS). An understanding of these effects, however, has been impeded by a widespread misconception that Raman-resonant FWM does not transfer energy between the lightwaves and the medium. The equations for the photon densities at each light frequency show that, in actuality, two medium excitations are created or destroyed for each photon produced by FWM. This point may be further clarified by consideration of the driving nonlinear polarization and by comparisons with broadband Raman conversion and nonresonant FWM. The Raman gain suppression effect may be understood qualitatively in terms of destructive interference between FWM and the usual stimulated Raman process.

Resumen
The stimulated Raman scattering gain of a multiline pump laser spanning a sufficiently wide spectral range is significantly reduced from that of a narrowband laser. This is due to destructive interference between the narrowband Raman effect and the Raman-resonant four-wave mixing effect which couples the lines together. However, this interference can be constrained to be always constructive by angle tuning of the pump and Stokes seed input beams to satisfy a phase matching condition for the four-wave mixing. The narrowband Raman gain will then be obtained. Calculations for a two-line XeF laser in a Raman conversion cell show that submilliradian beam angles can shorten the required cell length by factors of ~2, while loosening the pump intensity variation tolerance by an order of magnitude. Calculations for lasers with wider spectra indicate the potential for much larger gain increases and cell length reductions.

Resumen
Here CdSxSe1-x nanocrystals were studied and characterized by resonant Raman scattering, low frequency inelastic scattering, pressure tuned Raman scattering and photoluminescence. Ordinary Raman scattering and low frequency inelastic scattering were used for composition and size characterization. In the photoluminescence spectra we found that the deep defects where symbatic for compositions in the range close to CdS. For intermediate compositions down to CdSe no marked change in the defect peak positions were observed. This behavior is similar to the bulk case.1 Also the pressure coefficients in our measurements reflected this peculiarity. Resonant Raman scattering at different pressures was applied to examine the electron phonon interaction in the framework of the one dimensional configuration model. We found that the coupling strength (Huang-Rhys parameter) is larger than expected from theory and might indicate an extrinsic effect such as a point defect.2 The pressure dependence of the coupling was also compared with bulk CdS calculated from phonon replicas of the green defect line 3 and we found the same tendency of weakening with pressure. In the case of nanocrystals we were able to observe this beyond the phase transition point of bulk due to their higher stability or superpressure effects.

Resumen
Small particles and rough surfaces of certain metals are known to give anomalously high electric fields when illuminated with radiation resonant with the plasmon oscillation of these structures. The most widely publicized manifestation of the high field is the surface enhanced Raman effect. Equally dramatic but less well known is the large change in radiative and nonradiative rates for molecules near these structures. A reduction of fluorescence life time of 104 with no loss in quantum efficiency has been reported. This fast radiative rate has been used to give recovery in quantum yield of 103 for heavily quenched fluorophor. We present further studies on the extent to which radiative and non-radiative rates can be controlled using metal particle substrates. Self-quenching, surface treatment, scattering, and the difficult engineering associated with this method are discussed. Prospects for large scale production of substrates and application of the effect to quantitative fluorescence analysis is assessed. The direction of future study required to realize in practice the large demonstrated effects is presented.

Resumen
Gold nanoparticles absorb light efficiently at their resonant frequency and convert it to heat within several picoseconds. Strong laser irradiation onto those gold nanoparticles enables us to heat the surrounding materials locally and rapidly, which has been reported to be useful for cancer therapy, ultrasonic generation, microfluidic control, and so on. Because the gold nanoparticles can also act as sensing platforms for such as Raman spectroscopy under laser irradiation, development of the microfluidic control method with laser heating of gold nanoparticles is desirable to meet the requirements in lab-on-a-chip devices. Here, we present microfluidic manipulation techniques based on Marangoni effect controlled by laser heating of gold nanoisland films and our most recent outcomes.

Texto completo
Resumen
As much as 25% self-diffraction has been observed at the surface of n-GaAs:Te when two pumps (and a weak probe) intersect with an internal angle of 0.15 rad in the Raman–Nath regime. The photoinduced gratings decayed in less than 100 ps. The diffraction efficiency was nearly independent of sample thickness (40 μm and 350 μm), and careful investigation has shown that the diffraction arose primarily at the surface and was resonant just below the band edge. It is proposed that band-bending at the surface states causes increased absorption and results in a sheet of optically induced charge. The faster diffusion of electrons relative to holes allows a transient charge separation to a distance of one diffusion length (1 μm). As a result, a space-charge field is formed (Dember field) that can cause an index change through the Franz–Keldysh effect. The resulting transient grating can cause the large observed diffraction. This new BEST effect has potential for optical-switching applications.
