A High Gain and High Charge Carrier Mobility Indenofluorene-Phenanthrene Copolymer for Light Amplification and Organic Lasing

Amplified spontaneous emission with unprecedented gain values is demonstrated from thin films of novel blue-light-emitting indenofluorene-phenanthrene copolymers. In addition to their excellent photoluminescence properties, high charge carrier mobilities are observed, which makes these copolymers very promising for organic light amplifiers and lasers.
