All‐Inorganic Bismuth‐Based Perovskite Quantum Dots with Bright Blue Photoluminescence and Excellent Stability
Abstract
Lead halide perovskite quantum dots (QDs) possess color‐tunable and narrow‐band emissions and are very promising for lighting and display applications, but they suffer from lead toxicity and instability. Although lead‐free Bi‐based and Sn‐based perovskite QDs (CsSnX 3, Cs 2 SnX 6, and (CH 3 NH 3)3 Bi 2 X 9) are reported, they all show low photoluminescence quantum yield (PLQY) and poor stability. Here, the synthesis of Cs 3 Bi 2 Br 9 perovskite QDs with high PLQY and excellent stability is reported. Via a green and facile process using ethanol as the antisolvent, as‐synthesized Cs 3 Bi 2 Br 9 QDs show a blue emission at 410 nm with a PLQY up to 19.4%. The whole series of Cs 3 Bi 2 X 9 (X = Cl, Br, and I) QDs by mixing precursors can cover the photoluminescence emission range from 393 to 545 nm. Furthermore, Cs 3 Bi 2 Br 9 QDs show excellent photostability and moisture stability due to the all‐inorganic nature and the surface passivation by BiOBr, which enables the one‐pot synthesis of Cs 3 Bi 2 Br 9 QD/silica composite. A lead‐free perovskite white light‐emitting diode is fabricated by simply combining the composite of Cs 3 Bi 2 Br 9 QD/silica with Y 3 Al 5 O 12 phosphor. As a new member of lead‐free perovskite QDs, Cs 3 Bi 2 Br 9 QDs open up a new route for the fabrication of optoelectronic devices due to their excellent stability and photophysical characteristics.

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.
