Zn-Alloyed CsPbI3 Nanocrystals for Highly Efficient Perovskite Light-Emitting Devices
Abstract
We alloyed Zn 2+ into CsPbI 3 perovskite nanocrystals by partial substitution of Pb 2+ with Zn 2+, which does not change their crystalline phase. The resulting alloyed CsPb 0.64 Zn 0.36 I 3 nanocrystals exhibited an improved, close-to-unity photoluminescence quantum yield of 98.5% due to the increased radiative decay rate and the decreased non-radiative decay rate. They also showed an enhanced stability, which correlated with improved effective Goldschmidt tolerance factors, by the incorporation of Zn 2+ ions with a smaller radius than the Pb 2+ ions. Simultaneously, the nanocrystals switched from n -type (for CsPbI 3 ) to nearly ambipolar for the alloyed nanoparticles. The hole injection barrier of electroluminescent LEDs was effectively eliminated by using alloyed CsPb 0.64 Zn 0.36 I 3 nanocrystals, and a high peak external quantum efficiency of 15.1% has been achieved.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
