摘要
本文以聚丁(对甲苯硫酸)-2,4-己二炔-1,6-二醇酯[polylbis(p-toluene sulphonate)ester of 2,4-hexadiyne-1,6-diol](PDA-TS)单晶为例,分析其激光诱导光吸收机制,计算了单态和三态激子的结合能,认为PDA-TS中在1.35eV处的激光诱导光吸收峰是由于从~3Ag到~3Bu的跃迁所致,这与实验事实符合。
Photo-induced absorption in poly (bis (p-toluene sulphonate) ester of 2,4-hexadiyne-1, 6-diol) (PDA-TS) single crystal is studied theoretically. A mechanism of photo-induced absor-ption is proposed as exciton excitation. The binding energies for single and triple excitons are calculated and the photo-induced absorption peak at 1.35eV is considered as resulting from the transition 3Ag → 3Bu. This agrees with experimental data.
