描述了由氧化石墨烯-羧甲基纤维素复合材料制成的自支撑膜的制备和表征。利用透射电子显微镜、紫外-可见吸收光谱、拉曼光谱和热重分析完成表征。这种复合材料的非线性光学性能进行了研究,使用开放式孔径Z-扫描技术在纳秒制度,使用532 nm波长的激光。结果表明,该复合材料具有非线性光学性能,当与氧化石墨烯复合时,非线性光学性能大大增强。所有的现象表明,该薄膜是一个潜在的候选人的光限幅应用。
The preparation and characterization of free-standing films made of a graphene oxide-carboxymethyl cellulose composite material is described. Characterization was accomplished using transmission electron microscopy, ultraviolet–visible absorption spectroscopy, Raman spectroscopy, and thermal gravimetric analysis. The nonlinear optical performance of this composite material was studied using the open aperture Z-scan technique in the nanosecond regime using a 532-nm wavelength laser. Results show that the composite has nonlinear optical properties that are much enhanced when composited with graphene oxide. All phenomena indicate that the film is a potential candidate for optical limiting applications.
