Achieving trap-depth-tunable organic persistent luminescence through host energy-level engineering.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Recent studies have indicated that traps play a crucial role in determining characteristics of organic persistent luminescence, yet constructing traps with controllable depth remains highly challenging. Herein, we propose a host energy-level engineering strategy, which enables precise control of trap depth. Using the Randall-Wilkins method, the trap depth can be tuned from 0.38 to 0.72 eV without altering emission wavelength and the result aligns well with density functional theory calculations. Specifically, a host-guest material namely CPND@DPEPO, which has a deep trap of ~ 0.72 eV, exhibits deep-blue persistent luminescence lasting for 27 hours and efficient energy storage over 14 days at room temperature. By utilizing these trap-containing materials as the emission layer in organic light-emitting diodes, we develop a pixel-programmable information storage device. This work establishes a fundamental principle for designing organic materials with controllable trap depth, potentially expanding their applications in night tracing, military communication and biological imaging.
