The two-photon luminescence (TPL) of gold nanoparticles (NP) was shown to result from the excitation of hot carriers, the plasmonic NP resonances playing an important role both for plasmon enhanced absorption and plasmon enhanced emission. However, the exact parameters enabling to control or optimize the NP nonlinear luminescence still need to be understood in detail. In this paper, we report the two-photon excited photoluminescence of single gold nanorods exhibiting identical aspect ratio…

Two-photon luminescence of single colloidal gold nanorods: revealing the origin of plasmon relaxation in small nanocrystals
The two-photon luminescence (TPL) of small 10 nm x 40 nm colloidal gold nanorods (GNR) is investigated at the single object level, combining polarization resolved TPL and simultaneously acquired
From plasmon-induced luminescence enhancement in gold nanorods to plasmon-induced luminescence turn-off: a way to control reshaping.
It is shown that TPL reveals itself as a highly sensitive tool to follow tiny changes resulting from the photo-induced reshaping of GNRs, acting as feedback to stabilize the GNR shape and size.
Exploring the Relationship between Plasmon Damping and Luminescence in Lithographically Prepared Gold Nanorods
In order to engineer plasmonic structures for specific applications, the energy decay pathways upon photon absorption must be understood. One of the decay pathways is the emission of light. In this
Anti-Stokes Emission from Hot Carriers in Gold Nanorods.
Findings show that hot carriers and photoluminescence play a major role in the upconverted emission, as well as previous emission studies using ultrafast lasers, which gives the average number of participating photons as a function of emission wavelength.
Single-Particle Spectroscopic Studies on Two-Photon Photoluminescence of Coupled Au Nanorod Dimers
Noble metal nanoparticles exhibit interesting two-photon photoluminescence (2PPL) property which is important for their biomedical and photonic applications. Because of high-order sensitivity of
Tailoring and imaging the plasmonic local density of states in crystalline nanoprisms.
Two-photon luminescence microscopy is used to reveal the SP-LDOS in thin single-crystalline triangular gold nanoprisms produced by a quantitative one-pot synthesis at room temperature, allowing a new modal design of plasmonic information processing devices.
Effects of dyes, gold nanocrystals, pH, and metal ions on plasmonic and molecular resonance coupling.
The resonance coupling strength is found to approximately increase as the molecular volume-normalized absorptivity is increased and the resonance coupling can be reversibly controlled if the dye in the hybrid nanostructures is pH-sensitive and in the presence of metal ions.
Anomalous ultrafast dynamics of hot plasmonic electrons in nanostructures with hot spots.
General principles to enhance the generation of energetic electrons through specifically designed plasmonic nanostructures that could be used in applications where hot electron generation is beneficial, such as in solar photocatalysis, photodetectors and nonlinear devices are developed.
Light Emission from Gold Nanoparticles under Ultrafast Near-Infrared Excitation: Thermal Radiation, Inelastic Light Scattering, or Multiphoton Luminescence?
This work studies single particles and small clusters of particles by employing a spectrally resolved power-law analysis of the irradiation-dependent emission as a sensitive probe of these physical models, finding that in this regime, the experiments are compatible with both interband transitions and inelastic light scattering as the cause of the luminescence.
Photoluminescence of Gold Nanorods: Purcell Effect Enhanced Emission from Hot Carriers.
It is demonstrated, experimentally and theoretically, that the photon emission from gold nanorods can be viewed as a Purcell effect enhanced radiative recombination of hot carriers and the main photoluminescence peak coinciding with the longitudinal surface plasmon resonance.
