Summary: Light-emitting nanoparticles, known as quantum dots (QDs), have great potential for biosensing and bioimaging applications. However, their use in biological systems requires them to be water-dispersible without affecting their optical properties. In this study, researchers developed a new surface silanization method to preserve the optical properties of QDs and successfully prepared water-dispersible QDs.

Summary: In this work, HgSe/CdSe core/shell quantum dots (QDs) emitting at 1.7 μm were synthesized with a thick shell to increase the photoluminescence quantum yield. The quantum yield was measured to be 63% in nonpolar solvents, indicating the potential for even higher quantum yield when solubilized in water. Our findings highlight the importance of a thick type-I shell for achieving bright emission in the NIR-IIb region.

Summary: Giant shell CdSe/CdS quantum dots exhibit high brightness and flexibility, with near-unity quantum yield and suppressed blinking. However, their single photon purity is reduced due to efficient multiexcitonic emission. In this study, we observed a significant blueshift in the photoluminescence biexciton spectrum of pure-phase wurtzite quantum dots. By using spectral filtering, we achieved a 2.3 times reduction in biexciton quantum yield while preserving 60% of the exciton single photon emission, leading to an improvement in purity from g2(0)=0.07±0.01 to g2(0)=0.03±0.01. Furthermore, at higher pump fluence, the spectral purification was even more effective, resulting in up to a 6.6 times reduction in g2(0) by suppressing higher order excitons and shell states with larger blueshifts.

Summary: Treatment with superacid bis-(trifluoromethanesulfonyl) amide enhances the properties of optoelectronic materials, resulting in longer effective carrier lifetimes and higher photoluminescence quantum yields. A study on crystalline silicon and transition metal dichalcogenide monolayers and flakes shows that structurally similar chemicals give passivating films with different charge levels, and treatment with analogues to TFSA can enhance the photoluminescence of MoS2 and WS2.

Summary: Nanocrystal-sensitized triplet-fusion upconversion is an emerging strategy for converting long-wavelength, incoherent light to higher-energy output photons. The photophysics of tailor-functionalized CdSe nanocrystals were studied to understand energy transfer to surface anchored transmitter ligands, which can occur through correlated exciton transfer or sequential carrier hops. By reducing the barrier to hole-first sequential transfer, a significant acceleration of energy transfer was observed. This acceleration was found to be greater than the expected effect of increased carrier wave function leakage, indicating the dominance of sequential transfer under certain conditions. Transient photoluminescence measurements showed comparable quenching of NC band-edge and trap states by functionalization, suggesting a dynamic quasi-equilibrium allowing for extraction of photoexcitations even when a carrier is initially trapped.

Summary: The size-dependent pressure response of oleate-stabilized CdSe quantum dots in paraffin was investigated using diamond anvil cell experiments and density functional theory (DFT). The photoluminescence shows a blue-shift of around 43 meV/GPa for QDs above 3.0 nm, but the shift increases strongly for nanocrystals less than 3 nm in size. Conversely, the absorption shift is 45 meV/GPa above 3.0 nm but weakens to 35 meV/GPa for particles 1.5 nm in size. No crystallographic phase transitions occur below 2 GPa, and the optical effects are reversible. DFT calculations confirm that shifts in the bulk modulus begin for sizes estimated to be 1/2 of the Bohr radius, which we term the extreme confinement regime.

Summary: The fuel cell community has made a concerted effort to develop high activity oxygen reduction reaction (ORR) catalysts in order to reduce platinum group metal (PGM) content in proton exchange membrane fuel cells (PEMFCs). However, beyond just ORR mass activity, challenges include kinetic limitations in the hydrogen oxidation reaction (HOR) at the anode and transport limitations related to ionomer/catalyst interactions at the cathode. The critical role of the carbon support in these interactions has been revealed, emphasizing the importance of rational carbon structure design.
