Summary: La2O3:Pr3+ nanospheres were prepared by a urea-supported low-temperature thermal decomposition process. Characterization techniques such as XRD, FTIR, Raman, UV-visible, and photoluminescence were used to study the core and core-shell NSs. The results showed that the silica layer deposition over the core-NSs led to a reduction in diffraction peak intensities, a change in grain size, and a shift in the band edge. The core-shell NSs exhibited good aqueous dispersibility, colloidal performance, and multi-color luminescence transitions.

Summary: In this research, undoped CeO2 and Ce0.85La0.10M0.05O2 (M: Sm, Er, Y) compounds were synthesized by the hydrothermal method and their multi-functional properties were investigated. The addition of rare earth ions created oxygen defects in the compounds, affecting their electrical and luminescence behaviors. Characterization techniques such as XRD, BET, UV-vis DRS, SEM, PL spectroscopy, and EIS were employed to analyze the synthesized products. The compounds were found to be nanostructured and have a cubic phase. The total conductivity and bandgap energy of the compounds were calculated, and the emission spectra showed different colors depending on the additive type.

Summary: We fabricated undoped and (Te, Zn)-codoped n-type CuAgSe polycrystals successfully. The (Te, Zn) codoping on CuAgSe reduces the lattice thermal conductivity to about 0.3 W m(-1) K-1 at 673 K and increases the electrical conductivity. Particularly, a ZT value of 0.91 was achieved at 623 K, which is the highest ZT value in n-type CuAgSe. Therefore, the Te and Zn codoping is a potential way to improve the thermoelectric performance of n-type CuAgSe.

Summary: The environmentally benign Cs2NaInCl6 double perovskite has a wide band gap of about 5.1 eV, making it photocatively and photostable in the UV, visible, and SWIR regions. By doping lanthanide ions like Er3+ and Yb3+ into the octahedrally coordinated In3+ lattice site, SWIR radiation at 1540 nm and 994 nm can be emitted. However, the optical excitation of lanthanides is Laporte forbidden, and the host requires excitation energy >5.1 eV. To overcome this limitation, Te4+ was codoped with Er3+ or Yb3+ to transfer energy and emit SWIR radiation. Temperature-dependent measurements revealed the mechanism of energy transfer processes. A pc-LED emitting SWIR radiation was successfully fabricated.

Summary: The electron-hole pair in a CdSe/CdS core/shell nanocrystal shows different behavior under different confinement regimes. The reduction of optical bandgap is mainly caused by the change in the band-edge electron level. Additionally, the shift of electron levels can switch the energy order of transitions. The thermal distribution of electrons follows number-counting statistics.

Summary: Earth-abundant transition metal oxides, such as CoO and Co3O4, grown on carbon fiber paper (CFP) electrodes, exhibit different catalytic activities for the oxidation of glycerol, diols, and monohydric alcohols. In situ electrochemical tests show that the CoO/CFP electrode has higher catalytic activity than the Co3O4/CFP electrode, with lower interfacial impedance, higher charge transfer, and faster oxidation rate. The CoO/CFP electrode also produces value-added products with high selectivity and efficiency at low energy consumptions. Theoretical calculations highlight the importance of octahedrally coordinated Co-O sites in the adsorption, activation, and oxidation of C3-C1 alcohols. These findings provide insights for the design of highly efficient transition metal oxide catalysts for alcohol oxidation.
