Herein, by amplified spontaneous emission measurements, dithieno[3,2-b:2',3'-d]arsole (DTA)-bithiophene (DTA-BT) and DTA-ethynylbenzene (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 μJ, respectively, showing an outstanding high light-resistance among the polymer-based gain media.
在此，通过放大自发辐射测量，二噻吩并[3,2 - b:2',3'-d]砷杂环戊二烯（DTA）-联噻吩（DTA - BT）和DTA - 乙炔基苯（DTA - EB）聚合物薄膜在连续脉冲泵浦激发下，分别在泵浦能量为28.9和20.7 μJ时，至少15小时内表现出相当的光稳定性，在基于聚合物的增益介质中显示出优异的高耐光性。
