Impact of Cation Distribution on Photoluminescence of Ag-In-Se/ZnSe Core/Shell Nanocrystals.

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
Ag-In-Se/ZnSe core/shell nanocrystals exhibit good photoluminescence quantum yield (PLQY), yet intriguingly, the maximum PLQY is first reached after several days of storage. We hypothesize that this may be due to cationic rearrangement in the nanocrystal post-synthesis. To test this hypothesis, we computationally generated ternary Ag-In-Se and quaternary Ag-In-Zn-Se nanocrystals with varying degrees of cationic disorder, as quantified by the distribution of the metal cation valence electrons in the tetrahedra around Se anions. We then used density functional theory-parametrized tight-binding simulations to study the electronic structure and optical properties of these systems as a function of the homogeneity of the valence electron distribution in a tetrahedron. We found that homogeneous distribution of cations leads to a larger band gap and optical coupling, and that, in the presence of Ag
