我们应用了各种皮秒瞬态和连续波光学技术来阐明聚（对亚苯基亚乙烯基）纯膜和稀溶液的可溶性衍生物中激子的动力学、吸收和发射特性。我们发现薄膜和溶液中的光生单线态激子都具有强受激发射和光致吸收带的特征。我们证明这些波段可用于形成近红外光谱范围内具有可变切换时间的超快光学开关。 {版权} {ital 1997} {ital 美国物理学会}
We have applied a variety of ps transient and cw optical techniques to elucidate the dynamics, absorption, and emission properties of excitons in soluble derivatives of poly(p-phenylene vinylene) neat films and dilute solutions. We found that the photogenerated singlet excitons in both films and solutions are characterized by strong stimulated emission and {ital two} photoinduced absorption bands. We demonstrate that these bands can be used to form an ultrafast optical switch in the near IR spectral range with variable switching times. {copyright} {ital 1997} {ital The American Physical Society}
