Photoluminescence: Tailored Near‐Infrared Photoemission in Fluoride Perovskites through Activator Aggregation and Super‐Exchange between Divalent Manganese Ions (Adv. Sci. 7/2015)

Abstract

Tailoring near-infrared photoluminescence through activator aggregation and super-exchange between manganese ions in a perovskite lattice is presented by Q. Zhang, L. Wondraczek, and co-workers in article number 1500089, challenging the classical viewpoint where divalent manganese is used only for visible photoluminescence.
