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

Directly full-color frequency-upconversion under high-order multiphoton absorption (MPA) nonlinearities in NIR-III (1550-1870 nm) and NIR-IV (2100-2300 nm) windows is highly desirable for advanced photonics and bioimaging. However, it has remained beyond the reach of current materials due to their inherently weak high-order MPA. Here, we demonstrate that, driven by Bloch oscillations of excitonic dipoles after nonlinear polarization, giant multiphoton nonlinearities can be achieved in layered hybrid perovskites to enable full-color upconversion in NIR-III/IV windows. The MPA cross-section values of the designed three Ruddlesden-Popper perovskites are found to be several orders of magnitude larger than those of the reported MPA materials. These advancements facilitate versatile applications previously inaccessible in NIR-III/IV windows, including full-color upconversion displays and multicolor information encryption. Our work highlights the prospect of efficient high-order MPA and opens avenues for investigating excitonic quantum dynamics in high-order nonlinear optics.
