The quest for electrically pumped organic laser is now conducted in several places around the globe. In this paper we outline our approach to this long-term project and aim to describe both encouraging and challenging (discouraging?) results. We describe experimental results using polymers, polymer blends and triplet emitters in an LED configuration using either CW or pulsed mode of operation. We...
It has been shown that conjugated polymers possess the two basic requirements for electrically pumped lasers: (1) they can support optically-pumped lasing, and (2) they can support current densities of kA/cm 2 . However, electrically pumped lasing has not been realised yet. The above-mentioned prerequisites are sufficient when traditional III-V lasers are concerned. However, conjugated polymers...
