Interactions between surface plasmons (SP) of metallic surfaces and photoluminescence (PL) semiconductor nanocrystal (S-NC) have been extensively investigated, SP-induced PL enhancement has used as a sensitive analytical technique. However, this SP induced electrochemiluminescence (ECL) is rarely studied. In work, we report greatly enhanced ECL CdS thin films by gold nanoparticles (Au NPs) for ultrasensitive detection thrombin. The system was composed NC film on glassy carbon electrode (GCE)...
The quenching of electrochemiluminescence (ECL) from a CdS:Mn nanocrystal film by proximal Au nanoparticles was observed as result Förster energy transfer, while an enhancement ECL takes place after hybridization with target DNA due to the transfer excited surface plasmon resonances in AuNPs NCs at large separation, based on which ultrasensitive and specific biosensor constructed.
Photocatalytic hydrogen evolution from water has triggered an intensive search for metal-free semiconducting photocatalysts. However, traditional materials suffer limited efficiency owing to low intrinsic electron transfer, rapid recombination of photogenerated carriers, and lack artificial microstructure. Herein, we report a half-metallic carbon nitride highly efficient photocatalytic evolution. The introduced features not only effectively facilitate carrier transfer but also provide more...
The low quantum yield (∼10−5) has restricted practical use of photoluminescence (PL) from MoS2 composed a few layers, but the confinement effects across two-dimensional planes are believed to be able boost PL intensity. In this work, 2 9 nm dots (QDs) is excluded solvent and absorption spectra shown consistent with size distribution. QDs also found sensitive aggregation due effect.
Abstract The exploitation of the stable and earth-abundant electrocatalyst with high catalytic activity remains a significant challenge for hydrogen evolution reaction. Being different from complex nanostructuring, this work focuses on simple feasible way to improve reaction performance via manipulation intrinsic physical properties material. Herein, we present an interesting semiconductor-metal transition in ultrathin troilite FeS nanosheets triggered by near infrared radiation at room...
With DNA as a rigid spacer, Ag nanoparticles (NPs) were bridged to CdS quantum dots (QDs) for the stimulation of exciton-plasmon interactions (EPI) in photoelectrochemical (PEC) system. Due their natural absorption overlap, exciton QDs and plasmon NPs could be induced simultaneously. The EPI resonant nature enabled manipulating photoresponse via tuning interparticle distances. Specifically, photocurrent greatly attenuated even completely damped by generated EPI. work opens different horizon...
Tungsten trioxide dihydrate (WO3·2H2O) nanoplates are prepared by in situ anodic oxidation of tungsten disulfide (WS2) film on carbon fiber paper (CFP). The WO3·2H2O/WS2 hybrid catalyst exhibits excellent synergistic effects which facilitate the kinetics hydrogen evolution reaction (HER). electrochromatic effect takes place via intercalation into WO3·2H2O. This process is accelerated desirable proton diffusion coefficient layered Hydrogen spillover from WO3·2H2O to WS2 occurs atomic...
This work reports an aptasensor for ultrasensitive detection of thrombin based on remarkably efficient energy-transfer induced electrochemiluminescence (ECL) quenching from CdS:Mn nanocrystals (NCs) film to CdTe QDs-doped silica nanoparticles (CdTe/SiO2 NPs). CdTe/SiO2 NPs were synthesized via the Stöber method and showed black bodies' strong absorption in a wide spectral range without excitonic emission, which made them excellent ECL quenchers. Within effective distance energy scavenging,...
Eu(3+) doped CdS nanocrystals (CdS:Eu NCs) were synthesized via a co-precipitation method. The doping of ions caused 4-fold enhancement in electrochemiluminescence (ECL) intensity and more stable cathodic signals compared to pure NCs.

Boosted methanol production over MnO x /ZrO 2 catalyst could be achieved via plasma-assisted catalytic CO hydrogenation at ambient temperature and pressure.
Efficient electrochemiluminescence (ECL) quenching was achieved by functionalized CdTe quantum dots (QDs) through ECL energy scavenging, based on which ultrasensitive antigen detection could be realized.
By cutting MoS2 microcrystals to quantum dots (QDs) of sizes below 10 nm, the photoluminescence (PL) at ca. 450 nm can be detected easily due confinement effects across 2D planes. The PL is stable under continuous irradiation UV light but gradually quenches when treated with an increasing concentration hydrogen peroxide. Time-resolved and Raman spectra imply that H2O2 causes partial oxidation QDs. First-principles calculations reveal QDs oxygen impurity are indirect bandgap structures...
