Cadmium‐Doped Zinc Sulfide Shell as a Hole Injection Springboard for Red, Green, and Blue Quantum Dot Light‐Emitting Diodes (Adv. Sci. 15/2022)

Cadmium‐Doped Zinc Sulfide Shell as a Hole Injection Springboard In article number 2104488, Zhao Chen, Shuming Chen, Wai‐Yeung Wong, and co‐workers design an outermost cadmium‐doped zinc sulfide shell, which can be used as a hole injection springboard and makes the hole to be easily injected into quantum dot emissive layers step‐by‐step. It sounds like a pianist (hole) who walks up a staircase of piano key (cadmium‐doped zinc sulfide shell) and plays a beautiful piano music (efficient red, green, and blue emissions). [Image: see text]
