Short-range charge transfer for efficient ultra-narrowband deep blue afterglow.
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 4 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
Efficient and narrowband blue organic afterglow materials are critical components for advanced optoelectronic applications, but so far, have been rarely explored. Herein, we report short-range charge transfer-assisted high efficiency and ultra-narrowband deep blue (<450 nm) afterglow from a series of indolocarbazole-based chromophores. The short-range charge transfer within the fused π-conjugated frameworks enlarges the singlet-triplet energy gap and suppresses vibronic coupling and structural relaxations, thus leading to a slow reverse intersystem crossing rate, a long delayed-fluorescence lifetime of up to 186.48 ms and a high photoluminescence quantum yield of 86.1%. Notably, these afterglow emitters exhibit ultra-narrow full width at half maximum of 18 nm, presenting high colour purity with y colour coordinates below 0.05. Taking advantage of these unique afterglow features, the potential for encrypted light communications and high-resolution afterglow displays are demonstrated. This work not only provides an effective strategy for developing narrowband organic afterglow materials but also extends their applications to advanced fields.
