“… 176 Strong modifications of the emission characteristics of quantum dots in the presence of plasmonic nanoarrays were also demonstrated in ref ( 177 ), where coupling with the plasmonic modes was found to boost the spontaneous emission decay rate of quantum dots. Murai et al 178 studied the mechanism where photoluminescence from a thin Eu(III)-complex that would otherwise suffer total internal reflection and be trapped in the film could instead be recovered as emission into free space using SLRs. Periodic arrays of Al nanocylinders nanoparticles were used, and it was shown that directional photoluminescence enhancement as large as 5-fold can be achieved by excitation of SLRs.…”

When metal nanoparticles are arranged in an ordered array, they may scatter light to produce diffracted waves. If one of the diffracted waves then propagates in the plane of the array, it may couple the localized plasmon resonances associated with individual nanoparticles together, leading to an exciting phenomenon, the drastic narrowing of plasmon resonances, down to 1–2 nm in spectral width. This presents a dramatic improvement compared to a typical single particle resonance line width of >80 nm. The very high quality factors of these diffractively coupled plasmon resonances, often referred to as plasmonic surface lattice resonances, and related effects have made this topic a very active and exciting field for fundamental research, and increasingly, these resonances have been investigated for their potential in the development of practical devices for communications, optoelectronics, photovoltaics, data storage, biosensing, and other applications. In the present review article, we describe the basic physical principles and properties of plasmonic surface lattice resonances: the width and quality of the resonances, singularities of the light phase, electric field enhancement, etc. We pay special attention to the conditions of their excitation in different experimental architectures by considering the following: in-plane and out-of-plane polarizations of the incident light, symmetric and asymmetric optical (refractive index) environments, the presence of substrate conductivity, and the presence of an active or magnetic medium. Finally, we review recent progress in applications of plasmonic surface lattice resonances in various fields.

“…This is due to the enhanced probability of the electron transition of Sm 3+ from the ground state 6 H7/2 to the excited state owing to the intensified electric field near the Ag nanoparticles [38]. According to the selection rule, the transition probability is proportional to the square of the absolute value of dipole moment [39,40]. The optimal excitation wavelength for the 6 H7/2→ 4 G5/2 transition of Sm 3+ is λ = 400 nm, and the broadband SPR absorption peaks are in the range λ = 360-550 nm with the local maximum at λ = 425±20 nm.…”

Sm 3+-doped aluminoborate glasses containing Ag nanoparticles have been synthesizeed via a melt-quenching technique. After heat treatment, the surface plasmon resonance (SPR) absorption peak of Ag nanoparticles appears approximately at the wavelength  = 425 nm. With the precipitation of the Ag nanoparticles, the intensities of visible ( = 600 nm) and near-infrared ( = 950 nm) photoluminescence are enhanced under excitation at = 400 nm up to 39.8% and 25% that of the as-made glass, respectively. Moreover, the excitation of Sm 3+ at  = 473 nm for the sample heat-treated at 500°C shows higher enhancement in near-infrared photoluminescence by 55.5% ( = 950 nm). This enhancement is attributable to the intensified localized electromagnetic field accompanied by the excitation of SPR. The presence of Ag nanoparticles assists the conversion of UV light into visible and near-infrared light, which can induce a photoelectric effect for Si and other semiconductors used in solar cells.

“…Two factors can be modified at the emission wavelength: quantum yield (the ratio of the radiative decay rate with the nonradiative one) of the emitter via the Purcell effect [64] , and outcoupling (a process where the photoluminescence in the layer is diffracted out in a direction defined by the periodicity). [65,66] We investigate these lattice effects on the emission by simulating the light energy squared in the UCNPs layer upon irradiation with λ = 540 nm, corresponding to the 4 S 3/2 to 4 I 15/2 transition of Er 3+ (see Figure S7, Supporting Information). Compared to the large enhancement at λ = 980 nm, the enhancement is around two times, showing the Purcell effect is very small.…”

Aluminum (Al) is known as a plasmonic material effective in a wide frequency range up to the ultraviolet, while its plasmonic properties in the near infrared region have been less explored. In this study, up‐conversion (UC) photoluminescence is amplified by using an Al nanostructure to demonstrate that Al is a useful plasmonic material in the near infrared region as well. A periodic lattice of Al nanocylinders is selected as a plasmonic nanostructure, where the size of nanocylinder and the period of the lattice are tuned to match both the localized surface plasmon resonance and in‐plane diffraction to the absorption wavelength (λ = 980 nm) for the UC process. Core–shell‐type UC nanoparticles (NPs) are designed to suppress the energy transfer from NPs to Al cylinders which reduces the UC photoluminescence intensity. The resulting optimized core–shell UCNPs combined with the Al plasmonic lattice leads to over 100‐fold enhancement of UC intensity. The use of Al instead of conventional Au as a plasmonic material is beneficial from the point of view of low cost and abundance of element.
