Summary: A simple and cost-effective method to enhance the photoluminescence intensity of monolayer MoS2 using hexagonal symmetric Au metasurfaces is demonstrated. By tuning the localized surface plasmon resonances of the Au metasurfaces with nanospheres of different sizes, the photoluminescence signal of monolayer MoS2 can be significantly enhanced. This fabrication technique opens up a new pathway for plasmon-enhanced light-mater interactions of atomically thin two-dimensional materials.

Summary: This study introduces an effective strategy for modulating photoisomerization using a single near-infrared light source assisted by plasmonically enhanced photoswitchable upconversion photoluminescence. The strategy successfully substitutes the harmful high-energy light source with near-infrared stimuli, validates the reversible photoisomerization kinetics of photochromic molecules, and performs photodynamic imaging validation.

Summary: In this study, a novel core-shell hybrid structure of (mCu2-xS, NaYF4:Er/Yb)@ porous silica composites was constructed for upconversion luminescence (UCL). The amplified internal optical field of the composites, induced by the localized surface plasmon resonance (LSPR) coupling between Cu2-xS nanoparticles, allowed more photons to participate in the upconversion process. The UCL intensity of the composites in the emission band of green was 45 times higher than that of NaYF4:Er/Yb@SiO2, and the quantum yield of the composites was 1.32%. The UCL enhancement mechanism of the composites was also investigated.

Summary: In this study, horizontally aligned gold nanorod arrays with self-contained spacer and polarization-dependent plasmonic properties were prepared on silicon wafer substrates using a self-assembly method. The enhancement of upconversion luminescence of rare earth ions doped nanoparticles (NaYF4: Yb3+, Er3+) was investigated. Results showed that the luminescence intensity of the nanoparticles was greatly enhanced when the horizontally aligned gold nanorod arrays were used as a substrate. The self-contained spacer effectively prevented quenching of the luminescence and the arrays exhibited excellent optical polarization anisotropy.

Summary: In this study, incorporating silver nanoparticles (Ag NPs) and organic molecules (2,5-diphenyloxazole, PPO) into nanocrystals of CsPbBr3 enhances the X-ray radioluminescence (RL) efficiency. The charge transfer from PPO molecules to CsPbBr3 nanocrystals is improved by the plasmonic effect of Ag NPs, activated by X-ray-induced high-energy charges in PPO molecules. The Ag-NP-induced plasmonic effect reduces the photoluminescence FWHM of CsPbBr3 nanocrystals while maintaining the RL FWHM, thus improving RL efficiency by approximately 10%.

Summary: An improvement in random lasers based on quantum dot/graphene-doped polymer was observed, with the factors of multiple light-scattering and graphene surface plasmon resonance attributed to it. The study compared the emission characteristics of quantum dots doped with graphene oxide and reduced graphene oxide, and found that the hybrid of quantum dots and reduced graphene oxide exhibited a lower laser emission threshold. The emission modes and thresholds were strongly influenced by both the graphene doping concentration and the external temperature.

Summary: This study thoroughly discusses the effect of Yb3+ on NaErF4-based host-sensitized upconversion (UC) and provides mechanism interpretations. The results show that Yb3+ doping enhances the green UC emission in NaErF4 core nanocrystals, while it weakens the red UC emission in the shell. Furthermore, the UC emission intensity of core-inert shell nanoparticles can be influenced by the shell thickness and lattice mismatch.

Summary: Lanthanide-based upconversion nanoparticles (UCNPs) have attracted scientists' attention for their ability to convert tissue-penetrating near-infrared light into tailored optical illumination inside biological matter. These luminescent UCNPs have been widely used for background-free biorecognition and biosensing. Maximizing NIR light harvesting and upconversion efficiencies while protecting biological tissue is a challenge for laser-assisted photoactivation, and this review provides an overview of recent achievements and challenges in plasmon-modulated upconversion nanoformulations for biosensing applications.

Summary: In this study, we achieved significant enhancement of upconversion luminescence by utilizing long-range surface plasmon resonance mode. Compared to the reflection enhanced upconversion luminescence of Ag film, the intensity of upconversion luminescence was improved by 100 times with long-range surface plasmon resonance mode. Finite-difference time-domain simulation showed that incident light energy can concentrate in the upconversion nanoparticles doped dielectric layer at the long-range surface plasmon resonance mode, with a maximum electric field enhancement factor |E|2/|E0|2 reaching 58. Experimental results demonstrated that the enhancement of upconversion luminescence is related to the thickness of doped Polymethylmethacrylate (PMMA) layer. Additionally, the excited upconversion luminescence exhibited high directionality and could be received at specific angles.
