Novel framework achieves narrowband red emission in undoped LEDs, indicating improved efficiency and stability.

To develop a solid-state red light-emitting diode (LED) framework with narrowband emission and high operational stability.
Developed solid-state red carbon quantum frameworks (SSR-CQFs) with flexible alkyl chains.
Performed optical measurements to assess photoluminescence quantum yield and emission characteristics.
Fabricated solution-processed undoped LEDs using SSR-CQFs.
SSR-CQFs show a narrowband emission peak at 635 nm with a full width at half maximum of 39 nm.
Achieved a photoluminescence quantum yield of 64% in neat films.
UDLEDs based on SSR-CQFs exhibit a maximum external quantum efficiency of 8.04% and an operational stability of 116 hours at high temperatures.
