Capacitance measurements of a polarised liquid|liquid interface show that the capacitance of the interface increases in the presence of an adsorbed monolayer of citrate-coated gold nanoparticles. This unusual observation can be explained by an increase of the interfacial charge density or by an increase of the interfacial corrugation. This study shows that capacitance measurements provide a method to monitor metallic film formation at ITIES.

“…The enhancement was attributed to the electric field enhancement in the plasmonic hot-spots and the reduction of the fluorescence lifetime of dye molecules in close vicinity to the metal surface. 156 θ SPR is the angle of the incident light hitting the interfacial gold nanofilm that leads to a minimum (or dip) in reflectance at a specific wavelength. Also using a pseudo-Kretschmann configuration (see Figure 9A(i)), Hojeij et al produced clear experimental evidence of the dip in reflectance beyond the critical angle due to SPR absorption by the interfacial gold nanofilm, closely matching theoretical calculations; 89 see Figure 9A(ii) and (iii).…”

The functionality of liquid-liquid interfaces formed between two immiscible electrolyte solutions (ITIES) can be markedly enhanced by modification with supramolecular assemblies or solid nanomaterials. The focus of this Review is recent progress involving ITIES modified with floating assemblies of gold nanoparticles or "nanofilms". Experimental methods to controllably modify liquid-liquid interfaces with gold nanofilms are detailed. Also, we outline an array of techniques to characterize these gold nanofilms in terms of their physiochemical properties (such as reflectivity, conductivity, catalytic activity, or plasmonic properties) and physical interfacial properties (for example, interparticle spacing and immersion depth at the interface). The ability of floating gold nanofilms to impact a diverse range of fields is demonstrated: in particular, redox electrocatalysis, surface-enhanced Raman spectroscopy (SERS) or surface plasmon resonance (SPR) based sensors, and electrovariable optical devices. Finally, perspectives on applications beyond the state-of-the-art are provided.

“…Gold nanorods (GNRs) are highly suitable plasmonic nanomaterials for the large third-order nonlinear response resulting from the surface plasmons resonance (SPR) characteristics [14]- [20]. Surface plasmons (SPs) refer to the electromagnetic oscillations generated by the excitation of a free electron and an electromagnetic field in a metal surface region under an external electromagnetic field [21], [22]. Because of the spherical symmetry of the gold nanoparticles, free electrons oscillate uniformly in all directions, so there is only one SPR band [23].…”

We demonstrated the dissipative soliton generation from a passively modelocked ytterbium-doped fiber laser operating at 1041 nm by using evanescent field interaction with gold nanorods (GNR) saturable absorber (SA) experimentally. The GNRs, which have broadband longitudinal surface plasmon resonance absorption from ∼800 to ∼1500 nm, are synthesized by a seed-mediated growth method, and then composited with a D-shaped fiber to form the GNRs SA. The GNRs SA shows a modulation depth of 9.7% and low saturation intensity of 0.302 MW/cm 2 . With the proposed GNRs SA, a dissipative soliton fiber laser was achieved with pulse duration 162.3 ps, repetition rate of 6.649 MHz at 1041 nm for a pump power of 220 mW. In addition, the signal-to-noise ratio can reach ∼77 dB. The experimental result may make inroads for the nonlinear optical applications of the plasmonic nanomaterials.
