Abstract
A sample of TiO2 nanostructured was prepared using 8 molarity concentration of HNO3 diluted acid the preparation had been done by depending on hydrothermal method and using autoclave reactor with 100cc Teflon volume, at temperature (140 ˚C) , duration (10 h). The optical properties ,morphology and crystal structure of the nanostructure synthesized was investigated by using Field Emission Scanning Electron Microscope (FESEM), UV-V scanning , and the results revealed that the prepared specimen was rutile phase at mentioned acid molarity , temperature and duration ,the morphology imaging of this sample tell us that the mean radius of the TiO2 nano particles was about (117.1-148.3 nm).UV-V results revealed that TiO2 nanoparticles have indirect allowed band gab about 3.2 e.V and have refractive index about 1.1 -1.5.
