“…[ 19,24,27 ] Indeed, controlling the minimum distance between the plasmonic nanostructures (GNRs) and the luminescent UCNPs can avoid emission quenching through energy transfer from the UCNPs to the GNRs, since this process mostly happens for very small distances between both nanostructures.

“…This, together with the plasmonic fi eld's infl uence on the absorption and emission of UCNPs, can either enhance or quench the fi nal luminescence intensity (LI), depending on the distance between particles, which results in the existence of an optimal distance for luminescence enhancement. For instance, Wawrzynczyk et al [ 19 ] reported both luminescence enhancement of NaYF 4 :Tm 3+ , Yb 3+ , and luminescence quenching of NaYF 4 :Er 3+ , Yb 3+ in the presence of GNRs in a solution. In the past, works on the mutual effects of UCNPs and metallic structures in different confi gurations have been conducted, although they have mostly focused on the use of spherical metal nanoparticles.…”

A combined system of gold nanorods and NaGdF 4 :Er 3+ /Yb 3+ upconverting nanoparticles with double functionality, luminescence enhancement, and monitored heating is introduced. The paired nanostructures could become an excellent optical heater with thermal probe incorporated. To study their interaction, the longitudinal surface plasmon resonance of the gold nanorods is tuned to 980 nm, in resonance with the Yb 3+ absorption wavelength, so they can be simultaneously excited. Gold nanorods create a localized electromagnetic fi eld that enhances the emission intensity from upconverting nanoparticles. This luminescence enhancement is shown to depend on the interparticle distance and excitation power and, in this system, reaches a maximum enhancement of 9 for the green emission of Er 3+ ions. At the same time, evidence of strong collective heating from the gold nanorods is demonstrated. The temperature can be controlled by changing the excitation power and measured in situ via the Er 3+ thermally sensitive luminescence. At high excitation powers, the heating can trigger a deformation of the gold nanorods, which limits the maximum temperature achievable in the system to 160 °C. Combining these nanostructures provides an all-optical heating system with improved emission intensity that can monitor the temperature achieved.

“…After absorbing positively charged PAH on the surface by self‐assembly, the negative gold NPs were attached on the surface or used as seeds for further formation of the gold nanoshell. The UC luminescence intensity was enhanced 2.6 folds by attaching with gold NPs owing to local field enhancement and surface plasmon‐coupled emission effects . In comparison, the formation of a gold shell can significantly suppress the emission because of considerable scattering of excitation irradiation.…”

Lanthanide-doped upconversion nanoparticles (UCNPs) have been an emerging and exciting research field in recent years due to their unique luminescent properties of converting near-infrared light to shorter wavelength radiation. UCNPs offer excellent prospects in luminescent labeling, displays, bioimaging, bioassays, drug delivery, sensors, and anticounterfeiting applications. Along with the abundant studies and rapid progress in this area, UCNPs are promising to be a new class of luminescent probe owing to their special advantages over the conventional organic dyes and quantum dots. Among them, polymers play an important role to improve properties or endow new function of UCNPs such as for matrix materials, water solubility, linking active targeting molecules, biocompatibility, and stimuli-responsive behavior. This article briefly reviews the compositions, optical mechanisms, architectures of upconversion nanocrystals and highlights the works on various functional UCNPs/polymer nanohybrids as well as many new interesting fruits in applications.

“…This has been demonstrated using a specially designed Au pyramid array that enables further adjustment of the emission spectra due to the metal-mediated quenching of the green fluorescence on flat metal surfaces [39][40][41][42]. The power-dependent and nonlinear plasmon-enhanced upconversion process has also attracted considerable attention, and effective manipulation and utilization of the upconversion nanocrystals have been the focus of research [43][44][45][46][47][48][49][50][51].…”

Fluorescent rare-earth ions are useful for efficient energy transfer via multichannels with different properties. Tuning these transfer processes in functional rare-earth materials has attracted considerable attention to satisfy the various demands of diverse practical applications. In this study, strong tunabilities of cooperative energy transfer and nonlinear upconversion emissions are realized using (Yb 3+ , Er 3+ )/NaYF 4 nanocrystals with and without doped Mn 2+ ions by adopting a plasmonic nanocavity composed of a silver nanorod array. The plasmon nanocavity can not only increase the energy transfer between Mn 2+ and (Yb 3+ , Er 3+ ) but also significantly enhance the radiative emission. This reveals a prominent nonlinear gain in the nanocavity nanosystems. These observations suggest the prospective applications in the design and preparation of rare-earth nanocrystals with excellent tunabilities of multiple functionalities.
