Multi-walled carbon nanotubes (MWCNTs) are special form of carbon nano materials with amazing applications in many areas of research.MWCNTs were synthesized by anAtmospheric Chemical Vapor Deposition (ACVD) system then decorated on their surface with Copper Oxide (CuO) nanoparticles via the hydrothermal method. The prepared un-purifiedMWCNTs and purified MWCNTs were characterized by High Resolution Transmittance Electron Microscope (HRTEM), Xray Diffraction (XRD) and Raman spectroscopy. As well as the CuO/MWCNTs nanocomposite was characterized by HRTEM, XRD, Fourier Transform Infra-Red Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) Differential Thermal Analysis (DTA) and Raman spectroscopy. The results demonstrated the distribution of CuO nano particles on the …

The ability to functionalize multi-wall carbon nanotubes (MWCNTs) with organic semiconductors is a promising methodology to promote their use in multiple optoelectronic applications, especially at the visible region of the optical spectra. In this article, we investigate the structural, optical, and electrical properties of chemically synthesized MWCNTs hybridized with zinc phthalocyanine (ZnPc) molecules. Interestingly, the hybrid ZnPc-MWCNTs optical bandgap shifts towards the visible light at 2.6 eV instead of the near-infrared bandgap of the pristine sample at 1.2 eV. Besides, the ZnPc-MWCNTs hybrid exhibits enhanced p-n heterojunction photodiode characteristics that are signifcantly improved with temperature increase. Moreover, the I-V curves …
