Summary: Full electroluminescence white-light-emitting diodes (WLEDs) are a focus of research in the development of white light sources due to their potential and advantages in energy saving. Achieving white emission involves balancing the excitation of different color emissive centers, which is challenging due to the different bandgaps of the emitters. Regulating the energy distribution among the emissive centers is crucial for achieving white emission and improving the performance and color quality of WLEDs. Various energy regulation strategies have been proposed, promoting the development of full EL-WLEDs.

Summary: Perovskite light-emitting diodes (LEDs) are promising light sources for future lighting and display technologies. However, achieving yellow electroluminescence, environmental stability, and lead toxicity are challenges. By incorporating a hole-transporting polymer into the CsCu2I3 emitter, the electroluminescent performance of the LEDs is improved, resulting in significantly enhanced device performances. The external quantum efficiency of the yellow LEDs is increased by 8.5 times, and the half-lifetime reaches 14.6 hours, making them the most stable yellow LEDs based on perovskite systems reported so far.

Summary: By doping Sb3+ and Bi3+ ions into Cs2NaInCl6 single crystals, blue and yellow emissions were achieved, leading to white light emission with a quantum yield of 77%. This dual emission is attributed to self-trapped excitons (STEs) related to different [SbCl6]3- octahedra, with the blue emission resulting from limited Jahn-Teller deformation from Sb3+ doping and the yellow STE emission enhanced by Bi3+ induced lattice distortion and sub-band level formation. Tuning between warm and cold white light can be achieved by adjusting the Sb3+/Bi3+ doping ratio.
