: In this work pure zinc oxide and Iron doped zinc oxide (Fe:ZnO) thin films were deposited on glass substrates through sol–gel followed by spin-coating technique with different concentration of dopant. Then optical properties of the thin films were characterized using UV-Vis spectroscopy. The SEM image, exhibit that the average grain size of the synthesized powder was around 50-60 nm and its spherical shape morphology was confirmed. UV-Vis analysis reveals that all samples had high UV absorbance at the wavelengths below 400 nm and with high transparency at visible region. Also it can be seen that the transparency of the pure ZnO in the visible wavelength was about 85%. Moreover there is a red shift in absorption edge with increasing the concentration of Fe dopant.
