Summary: This study systematically investigated the effect of Ag nanowires (NWs) on the optical properties of optoelectronic polymer poly[2-methoxy-5-(2ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). The decoration of Ag NWs with an average diameter of 160 nm leads to improved absorption and photoluminescence ability due to the coexistence of localized surface plasmons and propagating surface plasmons. The results showed significant enhancement, with 180% improvement in absorption and 190% improvement in photoluminescence at around 630 nm. Furthermore, the Ag NWs were found to effectively suppress non radiative recombination and enhance radiative recombination.

Summary: This study investigates the propagation of SERRS light through a 1D HS between NWDs using end-type excitations. The results show that the propagation is influenced by the polarization direction, with profiles of bright short and dark long propagations. The properties are well explained by numerical calculations based on electromagnetism, which reveal a mechanism involving resonance coupling and energy transfer between different SP modes.

Summary: The polarization of emitted light from nanowire-particle junction is investigated, and it is found that the correlations can be effectively modulated by the particle position and the gap between the nanowire and particle. The polarization behavior can be changed from polarization maintainer to rotator by adjusting the wire-particle gap, and by moving the particle along the wire, the polarization behaviors can be tuned from positive to negative correlation. These findings are explained by the hybridization of wire-particle coupled mode and propagating surface plasmon polariton modes.

Summary: This report introduces a novel method to achieve random lasing in the diffusion regime, demonstrating a cylindrical microstructure cavity made of a silica polymer combination to overcome the issue of directionality in conventional random lasers. The study also showcases a random laser mediated by metal nanowire in a cladded microstructure for the first time, observing the lowering of threshold and spectral shift with nanowire concentration. Additionally, the directional laser emission with a narrow spectral line was achieved in experiments, characterizing the lasing modes in terms of emission wavelength, lasing threshold, and temporal evolution.

Summary: The chirality of the dispersion relations and propagation lengths of two fundamental modes in single silver nanowires coated by chiral TDBC were analyzed. Differences were observed between the modes coated by left and right TDBC, and the propagation length was found to decrease sharply due to the dissipation of TDBC. The study suggests potential applications in detecting chiral molecules based on the observed differences in dispersion relation and propagation length.

Summary: The unusual optical properties of laser-ablated metal surfaces are caused by the excitation of local plasmon resonances in nano- and microstructures, as well as the interaction of these structures through surface plasmon polariton waves. The analytical solution to the problem of surface plasmon polariton excitation is important, and it can be solved by considering the surface geometry as a superposition of harmonic Fourier components. This study demonstrates that the problem can be solved using a method for calculating guided-mode amplitudes in the presence of current sources.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
