Highly efficient green‐emitting Zn‐Ag‐In‐S (ZAIS)/Zn‐In‐S (ZIS)/ZnS alloy core/inner‐shell/shell quantum dots (QDs), realized by an exothermically generated ZIS inner shell, are presented by Y. R. Do and co‐workers in article 1602638. A photoluminescence quantum yield of 87% with a peak wavelength of 501 nm is achieved. Candidates for applications involve white down‐converted light‐emitting diodes (DC‐LEDs) providing high energy performance and ultrahigh color quality.
