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: This study explains how local excitation of gold nanorods (Au-NRs) causes a temperature increase in their vicinity and affects the properties of a model cell membrane. The results show that illumination of the Au-NRs changes the organization of the model membrane and makes it more stable and elastic. These findings are important for understanding how the photoactivation of nanoparticles influences the transport of medicinal substances.

Summary: Resonant control and enhancement of upconversion luminescence (UCL) of NaYF4:Yb,Er nanoparticles were achieved using multiplexed metal gratings. By designing doublet plasmon resonance modes at the excitation and green- or red-UCL emission wavelengths, or at the excitation wavelength and one of the emission wavelengths, the excitation/emission efficiencies of UCL were improved. Experimental results showed that matching the doublet plasmon resonance modes with both the excitation and emission wavelengths led to further UCL enhancements and significant modification of the emission intensity ratios. The mechanisms and resonance structures were investigated by analyzing the dependence of UCL emissions on excitation power and lifetimes. These principles and resonance structures can be applied to a broad range of optical phenomena involving photons of multiple frequencies.

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: This paper focuses on the development and utilization of novel semiconductor nanocrystals with remarkable localized surface plasmon resonance (LSPR) effect. Tungsten bronze nanocrystals with strong LSPR effect have been synthesized by introducing high valence metal ions, and the regulation and application of the corresponding LSPR effect are still being explored. Sn0.33WO3 nanocrystals with different crystal phases and morphologies were synthesized using different types of Sn precursors, and the acid radical ions provided by different types of Sn precursors were found to be an important factor affecting the LSPR absorption characteristics. The LSPR effect of Sn0.33WO3 enhances the excitation field of NaYF4:Yb3+, Er3+ nanocrystals, resulting in significant upconversion luminescence enhancement in the layered Glass/Sn0.33WO3/PMMA/NaYF4:Yb3+, Er3+ film.

Summary: Increasing interest has been observed in the design of photosensitizers. Most small molecular photosensitizers currently have limitations in penetration depth and photostability. In order to overcome these drawbacks, Frequency upconversion luminescence (FUCL) small molecules were used for photosensitizer design, as they offer deeper penetration, sensitive imaging, and improved photostability. A series of FUCL molecules with rigid structures (NIR-NH2, NIR-NHEt, NIR-NEt2) were developed, with NIR-NEt2 showing the highest generation of singlet oxygen, strongest upconversion luminescence intensity under 808 nm irradiation, and mitochondria-targeted ability. FUCL can serve as a superior molecular platform for image-guided photodynamic therapy of cancer cells.
