Summary: This Letter presents a fabrication process for current injection into micrometer-size Ag/GaAs Tamm emitting diodes with special care to avoid surface damages. Electroluminescence from GaAs quantum wells is demonstrated at room temperature, showing dispersion following the Tamm mode. Additionally, for small diameters Tamm structures, electroluminescence occurs in discretized energy modes due to in-plane confinement. This observation of electrically excited emission from a confined diode is a significant advancement towards Tamm plasmon optical devices with novel functionalities.

Summary: Currently available encapsulating materials for WLEDs have limitations, but this study developed promising materials with two significant advantages: direct encapsulation without phosphors and reprocessing for recycling. Blue-light-emitting vitrimers (BEVs) were prepared by reacting epoxy resin with amines, showing strong blue emission and fast stress relaxation. To achieve white-light emission, a well-designed yellow component was grafted into the BEVs, resulting in white-light-emitting vitrimers (WEVs). Using WEV as an encapsulating adhesive, stable white light with CIE coordinates (0.30, 0.32) was successfully achieved for 365nm LED chips without inorganic phosphors, indicating a promising future for WLED encapsulation.

Summary: In recent years, practical engineering applications such as fiber-optic gyroscope, wavelength division multiplexing, and optical coherence tomography have put forward higher requirements on light sources due to the rapid development of military, optical communication, biological imaging, and other fields. Amplified spontaneous emission (ASE) light source has become an excellent candidate due to its advantages such as suitable bandwidth, low coherence, and high power. This review analyzes the principle of the ASE effect, summarizes the optical gain properties of various gain materials and different structural types of electrically pumped ASE devices, and prospects the development of new ASE light-emitting devices integrated with high-gain materials and low-cost structures.

Summary: This study presents an improved efficiency design for white LEDs by integrating blue nanorod LEDs with green and red-emitting perovskite nanocrystal films. The design utilizes the localized surface plasmon effect of Ag@SiO2 nanoparticles to enhance the photoluminescence intensity of blue LEDs, while the high-power blue LED backlight improves the perovskite photoluminescence intensity. The resulting white LED with Ag@SiO2 nanoparticle-embedded nanorods demonstrates a 62% increase in photoluminescence intensity compared to planar white LEDs.

Summary: The phytochemical compounds in medicinal and agricultural plants have significant biological effects on human health, and these compounds are encapsulated in nanovesicles called exosomes. The yield, size distribution, and antioxidant properties of exosome preparations vary among different plant species. Artemisia absinthium exosome preparations had a remarkably higher yield and concentration, while Chelidonium majus and Hypericum perforatum samples showed the highest antioxidant activity per weight and per particle. There was no significant correlation between the antioxidant activity of plant material and nanoparticle preparations. Further biochemical analysis is needed to validate the biological activity of exosome preparations and their relation to source plant cells.

Summary: The study aims to improve the nutritional and sensory value of cultivated leafy vegetables by incorporating UV-A wavelengths into traditional visible spectrum lighting in controlled environment cultivation systems. Different genotypes of leafy vegetables were grown under LED lighting supplemented with UV-A or violet wavelengths. The results showed species-specific effects of UV-A/violet light on growth, antioxidant activity, and phytochemical contents of the vegetables, which were not correlated with untrained consumer's sensory evaluation scores. The 405 nm light was found to have higher antioxidant and/or sensory properties in kale, mustard, and green leaf lettuces, while both UV-A wavelengths reduced growth parameters in red leaf lettuce.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
