Summary: Energy conversion through exciting localized surface plasmon resonance in metallic nanostructures to generate hot electrons is an emerging strategy, with factors such as the size, shape, and materials of plasmonic metal nanostructures affecting the process. Manipulating the flow of hot electrons can be achieved by changing the size of plasmonic nanostructures on the metal-semiconductor plasmonic nanodiodes.

Summary: A dual-signal protocol was developed, combining electrochemical and optical detection methods using gold nanopit arrays, to improve aptamer-based biosensors. The non-fully penetrating AuNpA showed better plasmonic properties and enlarged the electrochemical active surface area compared to fully penetrating structures. The simultaneous use of electrochemical and optical transducers led to different detection limits, dynamic ranges, and sensitivities, providing new opportunities for disease diagnosis and point-of-care testing.

Summary: The energy loss in organic light-emitting devices (OLEDs) is mainly caused by the photons trapped in the waveguide modes associated with the organic-organic interface and the surface plasmon polariton modes associated with the metallic electrode-organic interface. Introducing gratings onto the metallic electrode is crucial for recovering the energy lost to the surface plasmon polariton modes. In this research, efficient outcoupling of the surface plasmon polariton modes in TE mode is demonstrated using a two-dimensional grating, resulting in a 62.5% increase in efficiency compared to a one-dimensional grating OLED. The efficient outcoupling of both the waveguide and surface plasmon polariton modes is verified through numerical simulation of the emission spectra and the field distribution.

Summary: Plasmonic nanoparticles based on copper were synthesized and capped with polymer to enhance ambient stability, leading to improved efficiencies in perovskite light-emitting diodes. The luminous efficiency can be increased by up to 115%, attributed to the plasmonic effects of the copper nanoparticles. The cost-effective polymer-capped copper nanoparticles may drive demand for plasmonic nanostructures in commercial optoelectronic devices.
