Abstract

A Zn0.9Co0.1O nanoparticles was made by a homogeneous precipitation method. Thin films of the same thickness of Zn0.9Co0.1O were deposited onto highly cleaned glass substrates by the thermal evaporation technique using modified source. Thin films of the same thickness have been exposed to plasma focusing with 0, 5, 10 and 15 shots. The structural characteristics of Zn0.9Co0.1O films were examined by X-ray diffraction (XRD) and scan electron microscope (SEM) before and after plasma focusing shots. The microstructure parameters, crystallites size and lattice strain have been found to reduce with increasing the plasma focusing shots. The optical properties were studied from their reflectance and transmittance in the spectral region in terms of the Murmann’s equation. The refractive index has found to decrease with increasing PF shots own to the reduction in film thickness. The energy gap has also found to decrease with increasing the plasma focusing shots.
