Zinc phthalocyanine (ZnPc) is an aromatic organic compound that exhibit semiconducting properties. This material is characterized by high thermal and chemical stability and optical absorption in the UV-VIS region. The ZnPc have a wide range of potential applications in the different fields such as sensors, organic thin film transistor, photovoltaic cells and others. In this study, we investigate the effect of the thin film thickness on the optical properties of the ZnPC. The knowledge of the optical properties is very important for better understanding the band structure and the energy band gap of this system. The ZnPc layers of different thickness ranging from 10 – 160 nm were prepared in the vacuum chamber by organic molecular evaporation technique. The pressure during the deposition process was about 3•10-4 Pa, the deposition rate was kept around 0,5 Å/s. The temperature of the evaporating ZnPc source was accurately controlled around 400 0C.
