Summary: This work reveals the mechanism of substitution of point defects by In ions in lithium niobate single crystals. It was found that In ions first replace Nb ions at Li sites, then Li ions. However, as the doping concentration reaches a critical value, the Li concentration reaches a maximum and the Li vacancies and niobium antisites remain constant. At this point, the crystal stops the introduction of indium. After this critical value, In replaces Li as well as the Li vacancies and niobium antisites.

Summary: By using the melt quenching technique, a lithium zinc borate glass with trivalent dysprosium ions (Dy3+) was synthesized, and its luminescence and lasing properties were investigated for white light generation. The synthesized glass was found to be amorphous according to the X-ray diffraction analysis. The optimized glass with 0.5 Dy3+ doping concentration exhibited a direct optical band gap of 2.782 eV and an indirect optical band gap of 3.110 eV. The photoluminescence spectrum showed emission bands at 659, 573, and 480 nm under 386 nm excitation, which were attributed to electronic transitions. The noncytotoxicity of the optimized Dy3+-doped LZB glass was confirmed through a cytotoxicity study using lung fibroblast cell lines. The results suggest that this glass could be a promising choice for white light-emitting diodes and lasers.

Summary: Ag-Mn2O3 was evaluated as a new photosensing material for detecting UV-visible-NIR radiation, and its performance was compared to single-phase Mn2O3. The Ag-Mn2O3 prepared by coprecipitation method showed significantly higher electrical current variations than Mn2O3, which can be attributed to a decrease in bandgap energy, the formation of metal-semiconductor heterojunctions, as well as the lower work function and higher free electron concentration of silver.

Summary: As nanocrystal-based optoelectronics advances, there is a need for advanced techniques to reveal the electronic structure of nanocrystals, especially under device-relevant conditions. Previous efforts have mainly focused on optical spectroscopy and electrochemistry, which require an absolute energy reference. In this study, we explored the use of photoemission microscopy as a strategy for investigating nanocrystal-based devices in real-time. The method was found to be applicable to different materials and device geometries, providing direct access to important information such as metal-semiconductor interface band bending and gate effect propagation distance.

Summary: We investigated the challenging CrCl3 surface using photon energy dependent photoemission (PE). By studying the core and valence electrons of cleaved single crystals in either ultra-high vacuum (UHV) or air, we confirmed the atomic composition with respect to the expected bulk atomic structure. The presence of a stable, but only partially ordered Cl-O-Cr surface was revealed by a common spectroscopic denominator. Through analysis of multiplet components, we quantified the electron charge transfer and the reduced crystal field due to the established polarization field. The methodology used in this study can have a significant impact on determining the structure of ordered sub-oxide phases in mono or bi-layer Cr trihalides.

Summary: HgTe is the only material capable of covering near-, short-, and mid-wave infrared due to its unique spectral tunability. Existing devices with transparent conductive oxide and gold electrodes are not completely suitable for the intended purpose. This study investigates the use of different metals (Au, Al, Ag, and Zn) and reveals that Ag causes dramatic transformations in Ag and HgTe. The careful choice of surrounding electrodes is crucial for HgTe devices, while Au and Al show stability in this transformation.

Summary: In this study, the magnetic properties of two-dimensional CrCl3 systems were investigated using density functional theory and Monte Carlo simulations. It was found that the introduction of Cl vacancies leads to a linear increase in magnetic moment, strengthening the ferromagnetic state and increasing the Curie temperature. Additionally, the presence of oxygen impurities results in the formation of a stable ordered phase, with antiferromagnetic coupling between chromium and oxygen atoms, giving rise to a two-dimensional ferrimagnetic hexagonal lattice system with a high magnetic ordering temperature.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
