We report the synthesis of nanocrystal heterostructures composed of CsPbCl3 and PbS domains sharing an epitaxial interface. We were able to promote the growth of a PbS domain (in competition with the more commonly observed Pb4S(3)Cl(2) one) on top of the CsPbCl3 domain by employing Mn2+ ions, the latter most likely acting as scavengers of Cl-...

We show how, in the synthesis of yellow-emissive Bi-doped Cs2Ag1–xNaxInCl6 double perovskite nanocrystals (NCs), preventing the transient formation of Ag0 particles increases the photoluminescence quantum yield (PLQY) of the NCs from ∼30\% to ∼60\%. Calculations indicate that the presence of even a single Ag0 species on the surface of a NC...

We report the composition-dependent optical properties of Bi-doped Cs2Ag1−xNaxInCl6 nanocrystals (NCs) having a double perovskite crystal structure. Their photoluminescence (PL) was characterized by a large Stokes shift, and the PL quantum yield increased with the amount of Na up to ∼22% for the Cs2Ag0.4Na0.6InCl6 stoichiometry. The presence of...
