Summary: This study presents a new type of SPR sensor fabricated using a multi-layer nanostructure Ag/Si3N4/Au, showing excellent performance in monitoring relative concentration of glucose. The sensor's performance is significantly enhanced by high strength of the evanescent electric fields associated with surface plasmon resonance, resolving glucose concentrations down to about a percent. Strong evanescent fields with long decay lengths contribute to the sensor's performance, facilitating the detection of changes in optical properties at large distances.

Summary: A tunable wavelength nanolaser based on Fe3O4@M (magnetic-plasmonic) core-shell NPs/metal film coupled structure was proposed in this article. The optical properties of the nanolaser with different core-shell NP sizes and gap distances between Fe3O4@M NPs and metal film were investigated using the finite element method. The wavelength of the nanolaser based on Fe3O4@Ag NPs/Ag film structure could be tuned from 415 to 810 nm, and that based on Fe3O4@Au NPs/Au film structure could be tuned from 536 to 779 nm by controlling the gap distance and NP size.

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.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
