Summary: The electroluminescence spectra of narrow-gap type II InAs/InSb/InAs heterostructures containing InSb quantum dots were studied. The luminescent properties of the heterostructures were investigated under forward and reverse bias in the temperature range of 77-300 K. Suppression of negative interband luminescence and dominance of interface recombination transitions were observed at the InSb/InAs type II heterojunction when applying reverse bias at room temperature. Recombination transitions involving localized electron-hole states of the InSb quantum dots were revealed and recorded at low temperatures.

Summary: By bonding Ho3+ doped ZnO microsphere onto p-GaN substrate, a heterojunctional LED is formed, which shows tunable electroluminescence in wavelength and chromaticity due to the light confinement effect in the ZnO microsphere and multilevel emission system in rare earth materials. The device exhibits broadband emission at 400 nm and sharp emissions from Ho3+ ions at various wavelengths under different driving biases. Furthermore, the wavelength and chromaticity can be controlled by the duty cycle or rate of forward and reverse driven biases under intelligent programmable AC driven, enabling a gradient from blueviolet light to white light.

Summary: This study presents a high-performance self-powered ultraviolet photodetector based on a single Ga-doped ZnO microwire covered by Ag nanowires and a p-type GaN wafer. The photodetector exhibits ultrafast response and high photosensitivity, with significantly improved responsivity and detectivity compared to a conventional ITO electrode. The enhanced performance is attributed to the higher optical transparency and better electrical properties of the Ag nanowires, as well as the plasmonic effect on ZnO:Ga, which enhances light absorption and photocurrent.

Summary: This study demonstrates the fabrication of superlattices by templated self-assembly of gold nanoparticles on a flexible support, with tunable lattice-plasmon resonances by means of macroscopic strain. It shows that the highest SERS performance is achieved by matching the lattice plasmon mode to the excitation wavelength, by post-assembly fine-tuning of long-range structural parameters.

Summary: Constructing heterostructures is an effective strategy for efficient photocatalysis, and the type of heterojunctions is determined by the charge carrier transfer path. Understanding the charge carrier transfer mechanism of heterojunctions is crucial for guiding the construction of rational heterojunctions. In this study, an S-scheme K6Nb10.8O30@Zn2In2S5 (KNbO@ZIS) heterojunction with a 1D/2D core-shell structure is designed to improve photocatalytic hydrogen production. The improved photocatalytic performance is mainly attributed to the suppressed charge carrier recombination and accelerated charge carrier transfer in the photocatalysts.

Summary: The complexation of tetracyclines with Fe species plays a significant role in the removal of tetracyclines by ferrate. Experimental results show that the complexation of tetracyclines with Fe3+ contributes to 79% of the overall removal, followed by oxidation (11%) and adsorption/flocculation (10%). Thermodynamic and kinetic calculations suggest that complexation reactions between Fe3+ and tetracyclines are more likely to occur than oxidation reactions between ferrate and hydroxyl radicals. The complexation rates of tetracyclines with Fe3+ determine the removal of multiple tetracyclines by ferrate, highlighting the importance of considering complexation in the removal of pollutants.

Summary: All-inorganic cesium lead bromide (CsPbBr3) quantum dots (QDs) have been reported as ideal gain materials for high-performance lasers due to their high photoluminescence (PL) quantum efficiency. However, isolated CsPbBr3 QDs have not achieved lasing emission (LE) because of their finite absorption cross-section. In this study, continuous-wave lasing of isolated CsPbBr3 QDs embedded in a microcavity is demonstrated, achieving stable single-mode lasing emissions with an ultra-low threshold and a high Q factor. These perovskite-based microcavity structures provide an excellent experimental platform for studying single-particle nano-lasers and quantum physics frontiers.
