Extended Data Fig. 4: Morphological and structural characterization of CQD:perovskite hybrid structures.
From: Lattice anchoring stabilizes solution-processed semiconductors
a, b, HRTEM (a) and fast Fourier transform (b) images of PbS quantum dots with a thin CsPbBrI2 perovskite shell. The shell has a lower contrast than the CQDs, as CsPbX3 has a lower density than PbS. c, d, Scanning TEM images and EELS elemental mapping of a CQD/CsPbBrI2 core–shell structure (c) and a CQD-in-CsPbBrI2-matrix structure (d).
