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

We report a facile, cost-effective, and environmental friendly supersaturated recrystallization method for synthesizing Copper (I) bromide quantum dots (CuBr QDs) at room temperature under ambient conditions. The synthesis of CuBr QDs and their optical behaviour under weak confinement remains largely unexplored, where CuBr is a non-toxic, earth-abundant semiconductor with intrinsic blue emission and promising optoelectronic properties. The optical properties of the synthesised QDs were tuned by tin (Sn) doping. Structural analysis confirmed the formation of phase-pure, crystalline QDs with an average particle size of 2.98 ± 0.44 nm for pure and 3.57 ± 0.39 nm for Sn-doped CuBr QDs. The X-ray photoelectron spectroscopy confirmed the oxidation state [Formula: see text], [Formula: see text], and [Formula: see text] and verified the successful incorporation of Sn into the CuBr lattice. Optical characterization shows an increase in bandgap from transitioning from bulk to QDs, resulting in blue emission, while Sn doping introduces dopant-related states that decrease the bandgap, causing a red-shift in emission color from blue to orange. This is accompanied by an extended photoluminescence lifetime from 490 ps to 970 ps and enhanced color purity up to 99.7%. These findings highlight the potential of Sn-doped CuBr QDs as efficient, eco-friendly candidates for orange-emitting solid-state lighting applications.
