Halide-Metal Complexes at Plasmonic Interfaces Create New Decay Pathways for Plasmons and Excited Molecules

Andrei Stefancu et al.

Summary: By modifying the chemical interface of silver nanoparticles with halide ions, the total decay rate of adsorbed excited molecules and the plasmon damping rate can be controlled. Halide-modified silver nanoparticles show an increased decay rate of excited molecules and stronger chemical interface damping compared to chloride-modified silver nanoparticles, pointing towards the formation of metal-halide surface complexes.

Enhanced luminescence of Eu-doped films based on gap coupled plasmons

Jinhua Liu et al.

Summary: Coupled plasmons have been investigated for their potential in enhancing luminescence. In this study, a gap coupled nanostructure consisting of Au nanorods, a space layer, and Ag nanoparticles was designed to enhance the photoluminescence of Eu film. The results showed a maximum enhancement factor of 53.5-fold. The Ag nanoparticles film enhanced the electromagnetic field, while the space layer adjusted the distance to reduce nonradiative energy transfer. The Au nanorods played a dominant role in luminescence enhancement due to their perfect match with the emission spectrum of Eu.

Broadened optical absorption, enhanced photoelectric conversion and ultrafast carrier dynamics of N, P co-doped carbon dots

Yatao Pan et al.

Summary: This study synthesized nitrogen and phosphorus co-doped carbon dots (N, P-CDs) and investigated the effects of phosphorus doping on the optical and photoelectric properties. The introduction of phosphorus atoms significantly changed the electronic structure of N, P-CDs, extended the absorption spectrum, and improved the light-harvesting ability. The carrier dynamics were also studied, showing decreased carrier recombination and efficient transfer of photogenerated electrons.

Surface Plasmon Enhanced Fluorescence Temperature Mapping of Aluminum Nanoparticle Heated by Laser

Naadaa Zakiyyan et al.

Summary: Partially aggregated Rhodamine 6G (R6G) dye is utilized as a lights-on temperature sensor to analyze the spatiotemporal heating of aluminum nanoparticles (Al NPs) embedded within a tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride (THV) fluoropolymer matrix. The use of a plasmonic grating substrate enhances the florescence intensity of the dye while improving optical resolution and heating rate of Al NPs, providing robust temperature sensing with sub-micron spatial resolution and temperature resolution on the order of 0.2 degrees C.

Hard core proof of the polyvinyl alcohol as a reducer for the formation of gold nanoparticles

Anurag Gautam et al.

Summary: This paper reports the direct synthesis of water dispersed gold nanoparticles encapsulated in polyvinyl alcohol (PVA) as a reducer and capping agent. The nanoparticles were found to have a fcc crystal structure with a size of around 22 nm, as confirmed by XRD and SEM analysis. The UV-visible analysis showed a surface plasmon resonance band at approximately 550 nm, confirming the formation of gold nanoparticles, which was further supported by EDX analysis.
