Summary: This study investigated the electrogenerated chemiluminescence behavior of luminol on a glassy carbon electrode modified with gold nanocluster-graphene-Nafion composite films in neutral aqueous solution. The composite films showed enhanced electrocatalytic activity towards the reduction of molecular oxygen, resulting in a strong cathodic luminol ECL response. Addition of hydrogen peroxide led to a decrease in the cathodic ECL response related to oxygen reduction and a new ECL response related to the electrochemical reduction of hydrogen peroxide was observed. The ECL response was linear with the concentration of hydrogen peroxide in the range of 1.0 x 10(-8) M to 4.0 x 10(-6) M with a detection limit of 2.21 x 10(-9) M in neutral aqueous solution.

Summary: The electrogenerated chemiluminescence (ECL) of luminol was investigated on a two-dimensional titanium carbide (MXene)-Nafion composite-modified glassy carbon (GC) electrode in a neutral aqueous solution. The MXene-Nafion composite solution was drop-cast onto the GC electrode surface, and the MXene exhibited strong electrocatalytic activity towards the reduction reactions of oxygen and hydrogen peroxide, resulting in strong cathodic ECL emissions of luminol. The ECL sensor based on the MXene-Nafion composite exhibited good selectivity towards hydrogen peroxide and could potentially be used as a transducer in oxidase-based biosensors.

Summary: In this study, sulfonated polyaniline (SPAN) was decorated on the surface of copper-based metal organic framework (HKUST-1) and functionalized by luminol to construct a chemiluminescence (CL) hybrid (SPAN/ HKUST-1@Luminol). The prepared hybrid exhibited excellent dispersion and stability in aqueous solution. Additionally, it showed significantly strong CL properties with a quantum yield 136 times higher than luminol. The hybrid demonstrated outstanding CL activity under both alkaline and neutral conditions, and was sensitive to hydrogen peroxide, enabling its use for detection in biological systems and monitoring of H2O2 production by living cells.

Summary: Chemiluminophores generate wide-band light emission through a chemical reaction without external light source. Plasmonic nanoparticles can enhance chemiluminescence quantum yield by accelerating radiative decay rate, while the catalytic action of metallic surface can increase the chemical reaction rate. Using an inert spacer layer on a silver metasurface may favor an electrodynamic mechanism for moderate chemiluminescence enhancement.

Summary: The study focuses on enhancing electrochemiluminescence (ECL) signals through modifying spherical Au nanoparticles supported by oxygen vacancy-rich CoAl-layered double hydroxide (LDH-O-v). The strong electronic metal-support interaction (EMSI) between Au nanoparticles and LDH-O-v significantly improves the luminol ECL signals, indicating potential for highly efficient ECL systems utilizing intrinsic catalytic activity of Au nanoparticles. This approach not only increases electron transfer efficiency but also opens up new possibilities for utilizing metal nanocatalysts in ECL signal amplification.

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.
