Superior light-resistant dithieno3,2-b:2 ',3 '-d arsole-based polymers exhibiting ultrastable amplified spontaneous emission

摘要

Herein, by amplified spontaneous emission measurements, dithieno 3,2-b:2',3'-darsole (DTA)-bithiophene (DTA-BT) and DTA-ethynyl-benzene (DTA-EB) polymer films exhibited considerable photostability under continuous pulsed pumping excitation for at least 15 h at the pumping energies, 28.9 and 20.7 mu J, respectively, showing an out-standing high light-resistance among the polymer-based gain media.
