“…This state leads to some important physical phenomena such as improved radiation rate, raised adsorption cross‐sections and energy interchange between exciton and plasmon. Meanwhile, weak coupling regime can be applied to SERS, [11‐15,32] surface‐enhanced fluorescence [33] and solar cells, [34] etc.…”

In this review, we focus on the summary of catalytic reaction driven by surface plasmons and plexciton, where the plexciton is the interaction between plasmon and exciton. We first review the reduction and oxidation reactions driven by plasmons, and analyze the role of plasmons in the two reactions. We then summarize the recent research on the surface catalytic reactions driven by plasmon‐exciton coupling and discuss the promotion effect of coupling interaction in oxidation reaction and reduction reaction. The coupling effect of plasmons and excitons can successfully improve the efficiency of catalytic reactions. Finally, this paper demonstrates the research progress in the electrooptical synergic plasmon‐exciton co‐driven surface catalytic reactions.

“…Other studies proposed doping with Ag, which has a significant effect but Ag has a high light-to-heat conversion efficiency and can cause cell apoptosis without targeting; therefore, Ag cannot be used in biological studies [7,8]. Many researchers proposed developing core-shell structures such as NaYF 4 : Yb 3+ /Er 3+ @NaGdF 4 : Yb 3+ and NaYF 4 : Yb 3+ /Er 3+ @NaNdF 4 : Yb 3+ /Tm 3+ @NaGdF 4 : Yb 3+ [9][10][11]. Alternatively, the material surface is covered with a biocompatible coating such as DSPE-PEG 2K and ICG [12][13][14].…”

In this study, a new method for synthesizing Ag-NaYF4:Yb3+/Er3+ @ SiO2 nanocomposites was introduced. Using a hydrothermal method, the synthesized Yb3+- and Er3+-codoped NaYF4 up-conversion luminescent materials and Ag nanoparticles were doped into up-conversion nanomaterials and coated with SiO2 up-conversion nanomaterials. This material is known as Ag-UCNPs@SiO2, it improves both the luminous intensity because of the doped Ag nanoparticles and has low cytotoxicity because of the SiO2 coating. The morphology of UCNPs was observed using scanning electron microscopy (SEM), and the mapping confirmed the successful doping of Ag nanoparticles. Successful coating of SiO2 was confirmed using transmission electron microscopy (TEM). Fluorescence spectra were used to compare changes in luminescence intensity before and after doping Ag nanoparticles. The reason for the increase in luminescence intensity after doping with Ag nanoparticles was simulated using first-principles calculations. The cytotoxicity of Ag-UCNPs@SiO2 was tested via the cell counting kit-8 (CCK-8) method, and its imaging ability was characterized using the micro-CT method.

In this study, a new method for synthesizing Au-NaYF4:Yb3+/Er3+-DSPE-PEG2K nanocomposites was introduced. Using a hydrothermal method, the synthesized Yb3+- and Er3+-codoped NaYF4 upconversion luminescent materials and Au nanoparticles were doped into upconversion nanomaterials and modified with DSPE-PEG2k up-conversion nanomaterials. This material is known as Ag-UCNPs-DSPE-PEG2k, it improves both the luminous intensity because of the doped Au nanoparticles and has low cytotoxicity because of the DSPE-PEG2k modified. Exciting UCNPs with a wavelength of 980nm near-infrared light will emit light with a wavelength of 520nm to further excite gold nanoparticles to convert light energy into heat. Successful synthesized gold nanoparticles was confirmed using transmission electron microscopy (TEM). The morphology of UCNPs was observed using scanning electron microscopy (SEM), and the mapping confirmed the successful doping of Au nanoparticles. Fluorescence spectra were used to compare changes in luminescence intensity before and after doping Au nanoparticles. The cytotoxicity of Au-UCNPs-DSPE-PEG2K was tested via the cell counting kit-8 (CCK-8) method, and its imaging ability was characterized using the Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) method.
