In this paper, the optical and structural properties of the prepared Cadmium hydroxide nanostructures by ultrasonic waves have been investigated by UV-Vis spectroscopy X-ray diffraction and Scanning Electron Microscopy (SEM).The results of analyses show that the band gap of cadmium hydroxide nanostructures is 3.95 eV, which in comparison with its bulk value, a blue shift nearly 1eV. Observed, which confirms the quantum confinement effect. Also the effect of Fe doping effects on the bandgap of the prepared cadmium hydroxide nanostructures. A comparison on the SEM image also shows by adding the Fe to the prepared nanostructures, it effects on the shape of the cadmium hydroxide nanostructures.
