Diffuse Spectrum

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.

ABSTRACTIn this paper, we used the Discrete Variational Xα, (DV-Xα) method to calculate the energy level of some rare earth doped BaF2 crystals and indicated that the Eu, Dy and Yb elements will change their valence from +3 to +2 under irradiation and thus change the optical properties of the crystals.The results show that this radiation effect model presented agree well with experiments.
