The β‐phase of poly(9,9‐dioctylfluorene) (PFO) shows a very low amplified spontaneous emission threshold because of its well‐resolved emission spectrum. Within the amorphous PFO, the β‐phase sites act similar to a dopant as they trap excitons and charges. The figure shows the blue‐light‐emitting β‐phase in a PFO solution.
