Summary: In this study, a new method has been developed to achieve high-resolution pixelated emission by controlling the thickness of transparent electrodes, resulting in a color-converting cavity that can selectively convert unpatterned quantum-dot white emission into saturated red, green, and blue emission. This method enables ultrahigh density red, green, and blue emission with a resolution of approximately 1700 pixels per inch, as well as achieving a color gamut of 111% NTSC.

Summary: A NC-NC Förster resonance energy transfer (FRET) system was developed in semiconductor nanocrystals, utilizing CsPbBr3 NCs as donors and CdSe/CdS NCs as acceptors. The system showed significant reductions in integrated photoluminescence intensity in toluene and octadecene solvents, with a Dexter energy transfer process leading to additional PL enhancement. This proposed system demonstrates improved lightconversion efficiency and anti-quenching properties, making it superior in light down-conversion applications.

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: This paper presents a novel light extraction structure called RaDiNa, which enhances the light extraction capability of top-emitting quantum dot light-emitting diodes (TE-QLEDs). By detaching a polydimethylsiloxane (PDMS) film from a ZnO nanorod (ZnO NR) layer and laying it on top of the TE-QLED, the RaDiNa-attached TE-QLED achieves significantly improved external quantum efficiency (EQE) compared to the reference device. This study provides essential information for the commercialization of TE-QLEDs.

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.
