Abstract

A study was conducted to investigate the effect of increasing generation on the photophysics and laser performance of a bis-fluorene cored dendrimer. It was found that increasing generation from (G1) to (G2) leads to a rise in the film PLQY from 42-75%. Researchers also fabricated dendrimer distributed feedback (DFB) lasers and an improvement in slope efficiency from 0.3-1.6% was observed as the generation increased. The performance of G2 dendrimer lasers was compared with a laser made by the process of spin-coating the gain material onto a corrugated substrate, using soft lithography. It was observed that the first generation dendrimer (G1) had one level of branching, while the second generation dendrimer (G2) had two levels of branching. The results show the benefits of using a soft lithographic technique, to provide feedback in organic DFB lasers.
