Summary: Lead sulfide (PbS) quantum dots were deposited on silica substrates by atomic layer deposition (ALD) to control their size. The size-controlled PbS QDs showed changes in growth orientation as the size of nanocrystals increased, with enhanced near-infrared luminescence and increased photoluminescence lifetime. The temperature-induced characteristics of the ALD-fabricated PbS QD films were also studied through annealing, showing different growth behaviors at different temperatures.

Summary: In this study, fiber-based PbS quantum dots as a saturable absorber were studied for the generation of dual-wavelength ultrafast pulses for the first time. By introducing PbS quantum dots saturable absorber into an erbium-doped fiber laser, the laser was able to simultaneously generate dual-wavelength conventional solitons with central wavelengths of 1532 and 1559 nm and 3 dB bandwidths of 2.8 and 2.5 nm, respectively. The results demonstrate the potential application prospects of PbS quantum dots as broadband saturable absorbers for ultrafast laser generation.

Summary: We achieved a low-cost and scalable synthesis of SWIR PbS quantum dot inks for the first time through an extensive investigation of reaction kinetics. The solar cell based on these PbS SWIR quantum dot inks exhibited a record-high power conversion efficiency of 1.44% with an 1100 nm cutoff silicon filter, and the photodetector device showed a low dark current density of 2x10(-6) A cm(-2) at -0.8 V reverse bias and a high external quantum efficiency of 70% at approximately 1300 nm. Our results realize the direct synthesis of low-cost and scalable SWIR quantum dot inks and may accelerate the industrialization of consumer SWIR technologies.

Summary: The effect of temperature on the photoluminescence emission of lead sulfide (PbS) and lead sulfide/manganese tellurite (PbS/MnTe) quantum dots was investigated. The results showed that as the temperature increased, the emission was blue-shifted and the emission bandwidth gradually increased, indicating electron-phonon interactions. Analysis based on the Boson model revealed stronger exciton longitudinal-optical-phonon coupling in the compound structure of PbS/MnTe compared to PbS.

Summary: Two-dimensional colloidal PbS nanosheets have a significantly higher exciton binding energy than their bulk counterpart, allowing for the generation of stable excitons at room temperature. The binding energy of the exciton increases as the thickness of the PbS nanosheet decreases, due to dielectric confinement. This large binding energy leads to a faster exciton radiative recombination rate, which has been confirmed experimentally.

Summary: In this study, the influence of Na2O concentration on the precipitation of CdSe quantum dots (QDs) in glasses is investigated. It is found that higher Na2O concentration leads to decreased connectivity and solubility of Se in the glass, resulting in the formation of Se-related clusters and lower temperature for the precipitation of CdSe QDs. In glasses with lower Na2O concentration, defect-related photoluminescence (PL) is suppressed and the overall PL changes from dual band to narrow band with tunable wavelength in the visible range. Glasses with higher Na2O concentration only exhibit dual band PL due to phase separation during high temperature heat-treatment. These results demonstrate that the PL properties of QDs in glasses can be modulated by adjusting the glass composition and structure.

Summary: CsPbX3 (X=Cl, Br, I) nanocrystals were successfully synthesized in fluorophosphate glasses for the first time, with controlled formation through adjustment of cooling rate and heat treatment conditions. The X-ray diffraction data and optical measurements confirmed the formation of 4-11 nm sized CsPbX3 nanocrystals, with the presence of two narrow bands in the luminescence spectra due to the introduction of two anions complicating the preparation process. The CsPb(Cl, Br)3 quantum dots exhibited high intensity photoluminescence with a quantum yield of 45-50% and narrow emission band.

Summary: Researchers have successfully synthesized wurtzite-phase HgTe nanorods using a two-step cation-exchange strategy. The residual Cu content in the final HgTe nanorods can be tuned by adjusting the solvent concentrations, and the photoluminescence peak position of the nanorods can be controlled by reducing the residual Cu content. Furthermore, field-effect transistors based on the synthesized HgTe nanorods exhibit favorable transport characteristics, and the photodetectors show high responsivity.

Summary: This study presents the preparation and characterization of an all-solid-state PbSe QD-doped glass fiber with tunable broadband MIR emission. A size-controllable PbSe QD-doped glass was prepared and achieved broadband tunable emission in the MIR regions of 1.8-2.8 μm. The PbSe QD-doped glass fiber was successfully prepared using the melt-in-tube melting method, and it was characterized using EPMA. There was no evidence of elemental migration in the glass fibers, which had a complete core-cladding structure. When excited by an 808 nm laser, PbSe QD-doped glass fibers produced broadband tunable emission within 1.8-2.8 μm, which was expected to be used as a broadband tunable MIR light source.

Summary: Recently, higher-order topological insulators (HOTIs) with topologically nontrivial boundary states have been extensively studied. A novel type of HOTIs called square-root HOTIs, where the topological nature comes from the square of the Hamiltonian, has been experimentally demonstrated in 2D photonic waveguide arrays written in glass using femtosecond laser direct-write techniques. The presence of edge and corner states at visible light spectra has been confirmed experimentally, and the dynamical evolutions of topological boundary states have been observed, suggesting potential applications in information processing and lasing.

Summary: Nanocrystal-in-glass composites (NGCs) are materials consisting of nanocrystals embedded in a glass matrix, allowing control over the phase, morphology, and luminescent performance of the nanocrystals. However, the thermal interaction between nanocrystals or nanocrystals and glass remains a challenge. To address this issue, a protective shell was introduced to expand the range of nanocrystal composition and to minimize interfacial reactions, resulting in efficient mid-infrared emission.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
