Summary: Epitaxial MgGa2O4 thin films were grown on a sapphire substrate by using metal organic chemical vapor deposition. The films showed high crystalline quality and low oxygen vacancy concentration after oxygen annealing. The oxygen-annealed MgGa2O4 photodetector exhibited excellent solar-blind ultraviolet photodetection characteristics, including quick response speed, low dark current, and high UV/Visible rejection ratio. The study also investigated the effects of annealing atmosphere on the film's photoelectric properties.

Summary: In this study, a smart strategy is proposed to achieve UV narrowband response by coupling Fabry-Perot microcavity with photomultiplication type organic photodetectors (PM-OPDs). The UV spectral selectivity of the optical microcavity can be optimized by tuning the thickness of the layers, leading to improved external quantum efficiency (EQE) of the PM-OPDs.

Summary: Vertically aligned zinc oxide nanorods were grown uniformly over a comb-shaped working area through a wet chemical method. The ZnO nanorods showed semiconductor-like behavior and exhibited substantial photoconductivity under UV light illumination. The conduction mechanism was found to involve small polarons at the grain boundary and correlated barrier hopping at the bulk/grain interface. The high photoconductivity can be attributed to the high surface-to-volume ratio of the nanorods and the generation of electron-hole pairs by UV light absorption.

Summary: A metal electrode modification process has been introduced for AlGaN-based MSM photodetectors to enhance the response of solar-blind UV light detection. The modification significantly increases the photocurrent and responsivity of the device by reducing the work function of the metal electrode and changing the height of the Schottky barrier. Moreover, adverse effects caused by surface state and polarization of AlGaN materials are effectively reduced, benefiting the improvement of electrical performances of III-nitride-based UV photodetectors.

Summary: Ultraviolet GaN photodetectors based on top-down strategies using nanowires (NWs) fabricated through nanosphere lithography and etching techniques demonstrate improved uniformity, morphology, and doping control. Measurements show a linear response of photocurrent to optical power, indicating that the dominant photodetection mechanism is the drift of photogenerated carriers at the junction, with negligible surface effects. These results demonstrate the unique properties of NW-based photodetectors that can be assessed through a scalable and low-cost fabrication process.

Summary: Organic photodetectors (OPDs) for near infrared (NIR) light detection, constructed by the sequential deposition (SD) method, exhibit high detectivity, reduced dark currents, and superior performance compared to devices made by blend casting (BC) method. The vertical phase segregation structure of SD devices leads to a significantly lower dark current, resulting in improved D* values under different bias voltages.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
