Highly Emissive Divalent-Ion-Doped Colloidal CsPb1–xMxBr3 Perovskite Nanocrystals through Cation Exchange
W Van der Stam, JJ Geuchies, T Altantzis… - Journal of the …, 2017 - ACS Publications
Colloidal CsPbX3 (X= Br, Cl, and I) perovskite nanocrystals (NCs) have emerged as
promising phosphors and solar cell materials due to their remarkable optoelectronic
properties. These properties can be tailored by not only controlling the size and shape of the
NCs but also postsynthetic composition tuning through topotactic anion exchange. In
contrast, property control by cation exchange is still underdeveloped for colloidal CsPbX3
NCs. Here, we present a method that allows partial cation exchange in colloidal CsPbBr3 …
