Summary: Non-rare earth Mn4+-doped oxide matrix phosphors have attracted increasing interest in the field of light-emitting diodes due to their excellent spectral properties. In this study, Mn4+-doped Mg2ScSbO6 phosphor was successfully synthesized and its crystal structure was determined using X-ray powder diffraction and Rietveld refinement analysis. The phosphor exhibited broadband absorption from near ultraviolet to blue light and deep red emission at approximately 682 nm. The photoluminescence intensity and decay lifetime of the phosphor were found to be strongly dependent on temperature, and the results of quenching analysis were reported. The optimized Mg2ScSbO6:Mn4+ phosphor exhibited high color purity of 99.4% and an internal quantum efficiency value of 61.93% modulated by charge compensation of Li+ ions. The photoluminescence peak position of the phosphor was well matched with the absorption peak of red and far-red phytochrome. Therefore, deep-red-emitting phosphors have great application potential in plant growth.

Summary: Novel and efficient broadband excited far-red emitting NaLiTi3O7:Mn4+ phosphors were synthesized. The phase purity of NaLiTi3O7 was analyzed using X-ray powder diffraction technique. The luminescence properties and fluorescence decay curves were explored to characterize the phosphors. Under UV/VIS excitation, Mn4+ doped NaLiTi3O7 shows intense emission around 681 nm. The crystal field strength (Dq) and Racah parameters (B and C) were determined to analyze the nephelauxetic impact of Mn4+ in the NaLiTi3O7 host lattice. The results are in good agreement with the linear dependency of 2E on the beta 1 parameter, which indicates the position of the Mn4+ emission based on beta 1. A Tanabe-Sugano energy level diagram was used to evaluate the luminescence process. Fluorescence decay measurement was used to discuss the concentration quenching phenomenon.

Summary: The electronic and optical properties of two-dimensional transition metal dichalcogenides can be tuned by doping strategy. In this study, spiral and monolayer Er-doped WS2 (WE) flakes were synthesized using ErCl3, WO3, and S as precursors. The growth and properties of WE flakes were systematically studied. It was found that the morphology, size, and thickness of WE flakes can be regulated by adjusting the molar ratio of ErCl3/WO3 and the growth time. The ErCl3 precursor acted as both the promoter of WE flakes' growth and the driver of screw dislocations formation.

Summary: Enhancing the near-infrared (NIR) photoresponse of molybdenum disulfide (MoS2) is achieved by synthesizing continuous Er-doped MoS2 (MoS2:Er) films. The enhanced NIR response is due to the absorption of Er3+ at 808 nm and 980 nm, as well as the increased traps introduced by Er-doping. The developed MoS2:Er/SiO2/p-Si heterojunction device has a fast response time, high detectivity, and wide bandwidth under 980 nm laser irradiation. The dark current can be suppressed for a period longer than 8 ms, and the heterojunction detectors can be used for NIR light communication.

Summary: In this study, a dual-emission fluoride phosphor, BaTaF7:Mn4+, was synthesized and its electronic structure and luminescence properties were investigated using density functional theory (DFT) calculations. The results showed that the unique dual emission and short fluorescence lifetime of the phosphor were due to the distortion of the local environment of Mn4+ ions, which tend to substitute for Ba2+ and Ta5+ in the host lattice. The white LED with BTF phosphor encapsulation achieved a high color gamut of 113.4% NTSC through RGB spectral filtering, suggesting its potential for display backlighting sources.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
