Abstract

ZnO nanopowders were prepared through a direct precipitation method, and then dipped into Yb(NO ₃) ₃ aqueous solution to obtain the Yb ³⁺-doped ZnO nanoparticles. The obtained ZnO nanopowders and its Yb ³⁺-doped products were characterized by XRD, FESEM, HRTEM, XPS, diffuse reflection absorption spectrum and spectrophotometry. The experimental results show that the obtained ZnO nanoparticles after calcinations at 500°C are hexagonal crystal phase with narrower particle size distribution. Moreover, the samples were employed for the photodegradation of Rhodamine B in an aqueous suspension, and it was found that suitable Yb ³⁺-doping levels can efficiently improve the photocatalytic activity of the obtained ZnO nanoparticles.
