以聚丁(对甲苯硫酸)-2,4-己二炔-1,6-二醇酯(Polylp-toluene sulphonate ester of 2,4-hexadiyne-1,6-diol)(PDA-TS)为例,研究了聚丁二炔(PDA)单晶中的光电导性;在分析了双分子成对复合的Onsager模型的局限性之后,提出了一个新的载流子被光产生的模型,并用它较好地解释了稳态光电流Iph对入射光子能量?ω依赖关系。The photoconductivity along the polymer hain direction for poly [bis(p-toluene sulpho-nate) ester of 2,4-hexadiyne-l,6-diol] (PDA-TS) single crystal is investigated. After analyzing the limitation of Onsager's model for bimolecular geminate pair thermalizing, a new model of photogenerated charge carries is presented and it is used to explain the dependence of stationary photocurrent Iph on the energies of incident photon.
