1 We reveal the existence of two different crystalline phases, i.e., the metastable rock salt and the equilibrium zinc blende phase within the CdS-shell of PbS/CdS core/shell nanocrystals formed by cationic exchange. Lead CDP-diacylglycerol synthase 1 Homo sapiens
2 The highest emission was achieved for chemically pure CdS shells below 1 nm thickness with a dominant metastable rock salt phase fraction matching the crystal structure of the PbS core. Lead CDP-diacylglycerol synthase 1 Homo sapiens
