摘要：

(Figure Presented) Self-cavity lasing from organic crystalline wires of a thiophene/phenylene cooligomer (BP3T), which is clearly evident in the inset spectrum (see picture), is reported. The BP3T crystalline wires show self-waveguided photoluminescence with a high internal quantum efficiency of photoluminescence. The efficiency at 300 K is estimated to be 0.8. The crystalline wires are epitaxially grown on KCl substrates using an improved growth technique. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
