Preparation of Rare Earth Doped ZnO Nano Particles and Investigation on their Optical Properties

Abstract:

Rare earth doped ZnO particles were synthesized by low temperature hydrothermal method. They showed fine pin-shaped growing along the C axial direction with the diameter about 9-48 nm. The structures of zinc oxide and La doped ZnO were characterized through X-ray powder diffraction (XRD), transmission electron microscope (TEM), Uv-vis diffuse spectrum (UV – vis DRS). Our results indicated that the doping of La results in the crystal cell of ZnO inflating, the band gap shift up to the ultraviolet region with the increase of La doping concentration.
