Optical properties of several transition metals, namely 3d (Fe, Ni, Co, Cu), 4d (Ru, Rh, Pd, Ag), and 5d (Os, Ir, Pt, Au) metals, for the application of surface plasmon resonance (SPR) were investigated. Using first-principles density functional theory method, we calculated the optical conductivities and the dielectric constant by including contributions from intraband and interband transitions. The calculated results for all systems reproduce the experimental trends qualitatively. The contribution of the Drude model is very dominant at low energy levels and gives a tail effect to the spectrum. Peaks in optical conductivity can be observed, which can be related to interband transitions. The SPR reflectance curve based on the Kretschmann configuration has further been simulated.

“…It can also be applied as a minute variable color filter. Surface plasmons can be excited on metal coated hemispherical Janus particles [27], so that the spectrum of the reflected light is varied depending on the incidence angle, because the resonance wavelength is sensitive to the angle [36]. From the fact that the direction of the particles can be precisely controlled by the electric and magnetic fields, as demonstrated here, light can be made incident on the particle at an arbitrary incident angle for the spectrum of the reflected light to be varied.…”

Hemispherical Janus particles that were coated with silver or nickel on the equatorial plane of hemispherical polymer microparticles were prepared and dispersed in water and the responses to AC electric and stationary magnetic fields applied were investigated. Both of the particles are so oriented that the equatorial plane is parallel to the AC electric field, owing to electric-field induced dipole orientation, which is the response proportional to the quadratic electric field. The nickel coated particles are self-assembled to make a chain-like structure aligned in the direction of the stationary magnetic field. In addition, when both AC electric and stationary magnetic fields are applied, the orientation of a nickel-coated hemispherical particle is uniquely determined in such a way that the equatorial plane is parallel to both electric and magnetic fields. Because the particle is magnetized on the plane, its direction is reversed when the magnetic field is reversed, which is the response that is proportional to the magnetic field. Utilizing these features, mirrors are fabricated that can switch the transmittance and reflectance with electric and magnetic fields. Such features of the Janus particles as to be controlled by an electric and magnetic fields will find wide applications in the fields of microoptics and microfluidics.

“…Plasmon resonance spectra (incident from the prism side) in the Kretschmann configuration and reflection spectra in the interband transition energy region (from air or prism side) were measured with a spectrophotometer (SolidSpec-3700 DUV, Shimadzu, Kyoto, Japan) or with a spectrometer with a cooled CCD. The experimental protocols for sample preparation and measurement to evaluate the plasmon resonance spectra of noble metals are described in detail in [17]. In this experiment, the surface plasmon was resonantly excited from the prism side by the CW pump from a laser diode at 408 nm, and the p-polarized probe white light from a laser-driven light source (LDLS, ENERGETIQ EQ-99) was incident from the air side at an incidence angle of 55 • .…”

“…The latter was focused into a sapphire plate to generate white-light continuum ranging from 470-630 nm with temporal duration of 100 fs to be used for broad-band monitoring. The incidence angle of the pump from the prism side was 45 degrees so that the pump energy was resonant with the plasmon in gold [17], and that of the probe from air was also 45 degrees. The wavelength resolution of time-resolved spectra was about 1.5 nm.…”

“…However, it is difficult for NOPA pulses to cover wavelengths shorter than 500 nm, so that silver and gold are not suitable samples, while copper matches best with the specifications of NOPA pulses. Although there is a limited number of studies on plasmons in copper, recently copper films of high quality have been fabricated, and recipes for sample preparation and detailed studies of copper plasmons have been reported [17,24,25]. We are presently preparing for pump-probe measurements in copper.…”

Plasmon Modulation Spectroscopy of Noble Metals to Reveal the Distribution of the Fermi Surface Electrons in the Conduction Band

Abstract:To directly access the dynamics of electron distribution near the Fermi-surface after plasmon excitation, pump-probe spectroscopy was performed by pumping plasmons on noble-metal films and probing the interband transition. Spectral change in the interband transitions is sensitive to the electron distribution near the Fermi-surface, because it involves the d valence-band to the conduction band transitions and should reflect the k-space distribution dynamics of electrons. For the continuous-wave pump and probe experiment, the plasmon modulation spectra are found to differ from both the current modulation and temperature difference spectra, possibly reflecting signatures of the plasmon wave function. For the femtosecond-pulse pump and probe experiment, the transient spectra agree well with the known spectra upon the excitation of the respective electrons resulting from plasmon relaxation, probably because the lifetime of plasmons is shorter than the pulse duration.
