The amplified spontaneous emission...

The amplified spontaneous emission (ASE) properties of oligo-phenylene/-thienylene organic semiconductors can be optimized by recrystallization from the melt, performed directly on-substrate. Upon laser irradiation, a gain-narrowing of one or more emission lines is observed, partially due to molecular alignment in the recrystallized phase. S. Hotta and colleagues report in the January 16th issue (see: Adv. Mater. 2002, 14, 119-122).
