Properties of light emitting organic materials within the context of future electrically pumped lasers

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.

Description
Summary: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 also describe results of modeling such structures with the aim of being able to design electrical and optical characteristics of future laser structures. Finally we describe an approach to modify material parameters so as to provide a range of building blocks for optoelectronic devices.
