Prussian blue analogues CoTCNi/HCCr and CoTCNi/HCCr/CNTs were stoichiometrically prepared by Co-precipitation method and the thin films deposited onto glass substrates via spin coater. XRD, Raman spectroscopy, EDX, SEM, and TEM techniques have been used to analyze the samples. The findings revealed the fabricated nanostructured materials of face-centered cubic (FCC) phase, in spherical shape decorated by CNTs. Transmittance ( T %) and reflectance ( R %) spectra of the thin films were measured in the wavelength range from 200 to 900 nm. The films exhibit high transparency more than 70% within the visible spectrum. Besides, the optical band gap ( E g ) was estimated showing blue shift caused by CNTs support.
