1 · What the graph read from it

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.

2 · The registry

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

Blue light-emitting diodes based on reduced-dimensional pure bromide perovskites have attracted increasing attention due to their superiority in achieving stable and efficient blue emissions. Yet, the employment of abundant insulating long-chain organic spacer cations severely limits the charge carriers transport capability and electroluminescence performance. Here, we utilize short-chain iminodi(methylphosphonic acid) ligand with two-terminated phosphonic groups that can strongly interact with the lead bromide octahedra via synergetic covalent bonds, facilitating the interlayer charge transfer and simultaneously reduces the defect density in perovskite films, thereby improving the light emission efficiency. Iminodi(methylphosphonic acid) ligand also enhances the dielectric confinement, leading to higher exciton binding energy and accelerated radiative recombination in perovskite emitters. The resulting blue light-emitting diode achieves a maximum external quantum efficiency of 25.4% and an operational lifetime exceeding 800 min, which represents a significant advancement among state-of-the-art blue light-emitting diodes based on pure bromide perovskites.
