In this current work, we have prepared zinc oxide (ZnO) nanorods by sol-gel method, and its composite films with a conducting polymer poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) also have been prepared by drop-casting method on the glass substrate. UV–Vis absorption and steady-state fluorescence studies revealed exciton dissociation and recombination at the interface of polymer chain and wide-bandgap semiconductor ZnO. Also, nonlinear optical properties of as-prepared nanocomposite films have been reported by employing an open aperture z-scan technique. A predominantly two-photon induced saturable absorption behavior, when excited with 532 nm, 10 ns laser pulses, appeared in nonlinear optical measurements. These results indicate that our as-synthesized composites can be useful in fabricating optical switch and saturable absorbers.

在目前的工作中，我们通过溶胶-凝胶法制备了氧化锌（ZnO）纳米棒，并且还通过滴加法制备了具有导电聚合物聚（3,4-乙撑二氧噻吩）聚苯乙烯磺酸盐（PEDOT：PSS）的复合膜。在玻璃基板上的浇铸方法。UV-Vis吸收和稳态荧光研究表明，在聚合物链与宽带隙半导体ZnO的界面处激子解离和重组。同样，已经报道了通过使用开孔z-扫描技术制备的纳米复合膜的非线性光学性质。在非线性光学测量中，当以532 nm，10 ns激光脉冲激发时，主要由双光子引起的可饱和吸收行为。
