TL;DR: In this paper, the authors demonstrate efficient blue electrophosphorescence using exothermic energy transfer from a host consisting of N,N′-dicarbazolyl-3,5-benzene (mCP) to the phosphorescent iridium complex iridium(III)bis[(4,6-difluorophenyl)-pyridinato-N,C2′]picolinate (FIrpic).

TL;DR: In this paper, an endothermic energy transfer from a molecular organic host (donor) to an organometallic phosphor (trap) can lead to highly efficient blue electroluminescence.

TL;DR: In this article, the authors demonstrate high-efficiency red electrophosphorescent organic light-emitting devices employing bis(2′-benzo[4,5-a]thienyl)pyridinato-N,C3′) iridium(acetylacetonate) [Btp2Ir(acac)] as a red phosphor.

TL;DR: In this article, an organic light emitting layer including a host material having a lowest triplet excited state having a decay rate of less than about 1 per second, and a guest material dispersed in the host material, the guest material having the lowest three-t excited states having a radiative decay rate greater than 1 × 10 5 or about 1× 10 6 per second.

TL;DR: In this article, a host material containing an emissive molecule is used to adapt to luminesce when a voltage is applied across the heterostructure, and the emissively selected molecule is selected from the group of phosphorescent organometallic complexes, including cyclometallated platinum, iridium and osmium complexes.
