Abstract

Ti doped Cu2O thin films were prepared at distinct Argon/Oxygen gas flow ratio of 34/1, 33/2,32/3 and 31/4 with net flow (Ar+O2) of 35 sccm by using DC magnetron sputtering system on glass substrates at room temperature. The gas mixture influence on the film properties studied by using X-ray diffraction, Field emission scanning electron microscopy and UV-Visible spectroscopy. From XRD results, it is evident that, with a decrease in oxygen content, the amplitude of (111) peak increased, peak at a 35.67o scattering angle and the films shows a simple cubic structure. The FESEM images indicated the granularity of thin films was distributed uniformly in a homogenous model and also includes especially pores and cracks. The film deposited at 31/4 showed a 98% higher transmittance in the visible region.
