Summary: Eu2+ doped Sr2MgSi2O7:Eu2+ nanophosphors were synthesized and their energy transfer behavior and temperature-dependent photoluminescence were investigated. The optimized SMSO:7Eu2+ NPs exhibited blue-shifted emission with increased temperature, with an activation energy of approximately 0.40 eV. The enhanced intensity and anti-counterfeiting properties of the optimized phosphor make it a promising platform for nUV-LED and LFP applications.

Summary: Many dental personnel use LED headlamps for hours every day, but it is unknown that these headlamps may pose a retinal 'blue light hazard'. This study found that LED headlamps emitted different radiant powers, emission spectra, and color temperatures, all of which increased the retinal 'blue light hazard' compared to a halogen source. Some LED headlamps had a greater 'blue light hazard' than the LED curing light.

Summary: NOBNacene is a rare example of a p- and n-doped nonacene compound with linearly extended ladder-type multiresonant thermally activated delayed fluorescence (MR-TADF) emission. It exhibits efficient narrow deep blue emission with a PL wavelength of 410 nm, FWHM of 38 nm, PL quantum yield of 71%, and delayed lifetime of 1.18 ms. The OLED using NOBNacene as the emitter shows a comparable electroluminescence spectrum with a peak at 409 nm and a maximum external quantum efficiency (EQE(max)) of 8.5% at CIE coordinates of (0.173, 0.055). The EQE(max) is increased to 11.2% with 3 wt% doping of the emitter in the emissive layer, resulting in a slightly broadened electroluminescence spectrum with CIE coordinates of (0.176, 0.068).

Summary: In this study, the metabolic responses of three Chinese cabbage varieties with different leaf colors after blue light treatment were investigated using widely-targeted metabolomics technology. The interior leaf color of orange varieties changed from yellow to golden yellow, while no visible color change was observed in the common variety. A total of 844 metabolites were measured from the leaf samples of these three varieties after short term blue light treatment, with several enriched nutritional metabolites identified. The orange Chinese cabbage varieties showed additional nutrition enhancement after the treatment. This study provides valuable insights on how to effectively use lighting conditions to enhance specific groups of nutrients in vegetables.

Summary: This study investigated the temperature dependence of electron leakage current in the AlGaN electron-blocking layer (EBL) of an InGaN/GaN blue light-emitting diode (LED) structure. Experimental results showed that the electron leakage current decreased significantly as the temperature increased, and this was consistent with simulation results. The counter-intuitive temperature dependence was attributed to an increase in potential barrier for electrons due to the increased ionized acceptor concentration in the EBL with temperature. The results were also consistent with the thermionic emission model and could provide insight into the thermal droop of GaN-based LEDs.

Summary: Recent studies have suggested that sound waves can regulate the growth, phytochemical contents, and stress responses of plants. This study found that different frequencies of sound waves could increase flavonoid contents and antioxidative properties, with a positive correlation between flavonoid accumulation and antioxidative effects in sprouts treated with specific sound wave frequencies. Sound waves may be a useful tool to enhance phytochemical contents in crops for functional products.

Summary: Plant abiotic stress responses are tightly regulated by different players at multiple levels, with RNA binding proteins (RBPs) increasingly recognized as critical modulators of stress responses. These RBPs have canonical/novel RNA binding domains and play a role in determining regulation of target RNAs according to plant requirements under given environmental conditions. Studies concerning the identification and functional characterization of RBP candidate genes are steadily increasing in importance due to their potential applications in genetic manipulation programs for improving key agronomic traits amidst climate anomalies.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.
