Light‐Emitting Diodes: Sensitized Yb3+ Luminescence in CsPbCl3 Film for Highly Efficient Near‐Infrared Light‐Emitting Diodes (Adv. Sci. 4/2020)

摘要

In article number 1903142, Ayumi Ishii and Tsutomu Miyasaka demonstrate near‐infrared light emitting diodes based on an energy transfer from wide bandgap all inorganic perovskite to ytterbium ions as an emitter in the crystalline film. The high light‐emitting efficiency around 1000 nm in the perovskite‐based diodes provides a new possibility for future optical applications.
