Özet
In this study, TiO2, TiO2/CoPc and CoPc films were prepared on microscope slide substrates using sol-gel spin coating method and the effect of CoPc additive concentration on the optical and structural properties of the films was investigated. A spectrophotometer in the 300-1100 nm wavelength range was used to measure the optical transmittance of thin films. Uv-Vis studies have shown transmittance of films decreases with increasing CoPc concentration in the intervals corresponding to the B and Q band absorption regions. Scanning electron microscopy (SEM) was used to characterize the surface morphology of thin films and it was observed that they were coated homogeneously. In the XRD measurements of annealed films, it was determined that the anatase-brookite mixed phase was observed in TiO2 films, while TiO2/CoPc films were anatase. Important parameters such as dislocation density, the crystal size of the films were calculated. © 2021, TUBITAK. All rights reserved.
