Jason D. Slinker,Jonathan Rivnay,Joshua S. Moskowitz,Jeffrey B. Parker,Stefan Bernhard,Héctor D. Abruña,George G. Malliaras +6 more
TL;DR: Ionic transition metal complexes (iTMCs) are receiving increased attention as materials capable of yielding efficient electroluminescent devices with air-stable electrodes as discussed by the authors, and their operational characteristics are dominated by the presence of mobile ions that redistribute under an applied bias and assist in electronic charge injection.

Electroluminescent devices from ionic transition metal complexes
TL;DR: In this paper, the authors used electric force microscopy to measure the in situ electric field profile across an ionic transition metal complex (iTMC) device and discerned its operation to conform to an electrodynamic model of operation.

TL;DR: It is shown that obtaining the appropriate boundary conditions is essential for capturing the underlying device physics in LEECs and that accumulation and depletion of mobile ions near the electrodes create high interfacial electric fields that enhance the injection of electronic carriers.
