Abstract: The characterizations of TiO2 nanoparticles which prepared on FTO conductive glass bases using the hydrothermal method with different temperatures (140,160,180) for 4 h, were studied after and before annealing. The XRD patterns were appeared that the samples preparation an increase in the intensity of the peaks and a decrease in the width of the FWHM peaks was observed due to the increase in temperature as well as an increase in the grain size as the distance between the grains decreased. UV-VIS tests demonstrated optical properties, including absorption and transmission. The increase in temperature effect at the absorption edge. It was shifted towards higher energies, that is, in its preferred direction. FESEM images were showed change an increase in the density of the substance upon increasing the temperature.
