Abstract Hybridized local and charge‐transfer (HLCT) excited‐state compounds that enable full exciton utilization through a reverse intersystem conversion (RISC) from high‐lying triplet to singlet state have attracted attention. Developing high‐performance ultraviolet (UV) blue organic light‐emitting diodes (OLEDs) is challenging due difficulties acquiring HLCT molecules with large energy bandgap high photoluminescence. Herein, new strategy for excellent‐performance UV emitters based on...
Oxygen solute strengthening is an effective strategy to harden alloys, yet, it often deteriorates the ductility. Ordered oxygen complexes (OOCs), a state between random interstitials and oxides, can simultaneously enhance strength ductility in high-entropy alloys. However, whether this particular mechanism holds other alloys how these OOCs are tailored remain unclear. Herein, we demonstrate that be obtained bcc (body-centered-cubic) Ti-Zr-Nb medium-entropy via adjusting content of Nb oxygen....
Host materials are indispensable for the fabrication of organic light-emitting diodes (OLEDs) with phosphorescent emitters, but high-quality host that can efficiently and simultaneously function in blue, green, red OLEDs (PHOLEDs) much rare.

Corrosion-erosion performances of Ti-6.5Al-2Zr-1Mo-1V (TA15) alloy fabricated by two laser additive manufacturing technologies, namely selective melting (SLM) and metal deposition (LMD) were investigated, compared with those traditional forged counterpart. Results show that SLM-ed TA15 possesses better corrosion, wear, tribocorrosion resistances than LMD-ed TA15. This is mainly attributed to the ultrafine-grain αʹ phase in microstructure sample, which improves hardness thereby enhances wear...
