摘要

In article number 1808377, Huaibin Shen, Lin Song Li, and co‐workers fabricate light‐emitting diodes with an external quantum efficiency >30% by exploiting Zn1−xCdxSe core/shell quantum dots with ZnSe as the intermediate layer and ultrathin ZnS. The maximum brightness achieved is up to 334 000 cd m−2, and the operational lifetime is extended to ≈1 800 000 h at 100 cd m−2.
