【摘要】：使用喷涂法制备了四苯基卟啉锌(ZnTPP)薄膜及ZnTPP-单壁碳纳米管复合薄膜。采用金相显微镜、扫描电子显微镜、台阶仪、四探针测试仪、紫外-可见光分光光度计、傅里叶红外光谱仪对薄膜的形貌、电学及光学性能等进行了系统的测量,研究了ZnTPP薄膜及ZnTPP-碳纳米管复合薄膜的太赫兹响应特性。结果表明,ZnTPP的太赫兹指纹谱峰为44,57,77,88,95和102cm-1,与文献[3]报道的棕树叶中叶绿素的指纹谱峰基本一致。重要的是,通过与碳纳米管相复合的方法,不仅使ZnTPP有机薄膜的均匀性及致密性得到了改善,还使后者的导电性及在紫外到太赫兹波段的光吸收性能获得明显增强。此外,还发现了复合薄膜在47及66cm-1处出现新的太赫兹吸收峰,证明了碳纳米管和ZnTPP之间存在的相互作用。这种作用使复合薄膜的综合性能得到提高。结果表明,通过加入碳纳米管,能够对ZnTPP的薄膜质量以及电学和光学性能等进行有效的改善,使之具有综合优良的物理性能、具备光电器件的应用前景。研究成果对促进有机物的太赫兹光谱研究以及寻找新型太赫兹有机敏感材料等具有重要意义。
[Abstract]:Tetraphenylporphyrin ZnTPPfilm and ZnTPP- single walled carbon nanotube composite thin film were prepared by spraying method. Metallographic microscope, scanning electron microscope, step tester, four-probe tester, UV-Vis spectrophotometer were used. Fourier transform infrared spectroscopy (FTIR) has systematically measured the morphology, electrical and optical properties of the films. The terahertz response characteristics of ZnTPP thin films and ZnTPP- carbon nanotube composite films are studied. The results show that the THz fingerprint peaks of ZnTPP are 44 / 57, 77 / 77, 8895 and 102 cm ~ (-1), which are consistent with those of chlorophyll in brown leaves reported in [3]. By combining with carbon nanotubes, the uniformity and density of ZnTPP organic films are improved, the conductivity of the latter and the optical absorption properties from UV to terahertz are greatly enhanced. A new terahertz absorption peak at 47 and 66 cm ~ (-1) is also found, which proves the interaction between carbon nanotubes and ZnTPP. The comprehensive properties of the composite films are improved by this interaction. The results show that, by adding carbon nanotubes, It can effectively improve the film quality, electrical and optical properties of ZnTPP, and make it have excellent physical properties. The research results have great significance in promoting the terahertz spectroscopy of organic compounds and finding new terahertz organic sensitive materials.
