“…It has been recently proposed and demonstrated that SLRs lead to an enhanced and modified emission of sources in the proximity of the array of nanoparticles [39][40][41][42]. In this section we demonstrate the modified emission of the YAG:Ce layer simultaneously coupled to quasiguided modes and SLRs.…”

“…With such a versatile system, the possibilities to tailor the emission from extended sources (e.g. thin layers of luminescent molecules or quantum dots) are many [20][21][22][23][24]. Previous work in this direction has focused on the interaction of SLRs with luminescent excitons in the weak coupling regime, which can even lead to photon lasing [25].…”

Abstract:We demonstrate the strong coupling of surface lattice resonances (SLRs) -hybridized plasmonic/photonic modes in metallic nanoparticle arrays -to excitons in Rhodamine 6G molecules. We investigate experimentally angle-dependent extinction spectra of silver nanorod arrays with different lattice constants, with and without the Rhodamine 6G molecules. The properties of the coupled modes are elucidated with simple Hamiltonian models. At low momenta, plasmon-exciton-polaritons -the mixed SLR/exciton states -behave as free-quasiparticles with an effective mass, lifetime, and composition tunable via the periodicity of the array. The results are relevant for the design of plasmonic systems aimed at reaching the quantum degeneracy threshold, wherein a single quantum state becomes macroscopically populated.

“…Light emission from emitters in the proximity of these systems has been recently reported. [12][13][14][15][16][17][18][19] Collective plasmonic resonances lead to the enhanced and directional emission that has been proposed for the improvement of the performance of white LEDs.

We investigate the luminescent spectrum of thin films of dye molecules embedded in a polymer layer and on top of an array of aluminum nanoparticles. The emission couples to quasi-guided modes that are efficiently coupled out to free space by scattering with the particle array. This outcoupling provides a significant enhancement of the emission in defined directions. The mode density changes and the spectrum is modified by varying the thickness of the layer. In consequence, the luminous efficacy of the layer of dye can be controlled by the layer thickness and the characteristics of the particle array. This system can be regarded as a luminescent metamaterial with designed properties that can be exploited in The invention of the efficient blue Light Emitting Diode (LED) 1 has led to the Solid State Lighting (SSL) revolution that will replace inefficient incandescent and fluorescent lamps by much more efficient light sources. Blue light is necessary for the generation of broadband white light. In a white LED this generation is usually realized through a luminescent or phosphorescent material, which is called the phosphor.2 Blue light from efficient InGaN quantum wells is absorbed by the phosphor, which emits light of a longer wavelength. White light is generated by mixing the emission of the phosphor with the fraction of non-absorbed blue light. Research on light generation in white LEDs has mainly focused on the improvement of the quantum efficiency of the phosphor by modifying the material composition and on the change of the emission spectrum in order to optimally match it to the photopic sensitivity curve of the eye. 3In this article we demonstrate a radically different approach to modify the emission intensity and spectrum of phosphors for SSL. This approach relies on coupling the emission to quasi-guided modes in the phosphor layers. These modes are very efficiently outcoupled to free space radiation by scattering with periodic arrays of metallic nanoparticles. Metallic nanoparticles support localized surface plasmon polaritons (LSPPs), which are the coherent oscillations of the free charges in the metal driven by the electromagnetic field. 4 LSPPs are resonant phenomena leading to the increase of the polarizability of the particle and, consequently, to the scattering efficiency. 5 In order to use resonant plasmonic nanoparticles in real applications, we need to have large arrays or ensembles of these nanostructures. Therefore, we investigate the modification of the emission from phosphor layers on top of periodic arrays of metallic nanoparticles. These and similar arrays have received recently a significant attention because of their capacity of supporting collective plasmonic resonances. These collective resonances are the result of the enhanced radiative coupling of LSPPs through scattering and diffraction by the particle array. Two different kinds of collective resonances in periodic arrays of plasmonic particles have been described in the literature. 6 The first kind arises in waveguides with the particl...
