Deep Blue Exciplex Organic Light‐Emitting Diodes with Enhanced Efficiency; P‐type or E‐type Triplet Conversion to Singlet Excitons?
TL;DR: It is shown that the majority of the delayed emission in electroluminescence arises from P-type triplet fusion at NPB sites not E-type reverse intersystem crossing because of the presence of the NPB triplet state acting as a deep trap.
