摘要：
The undoped and dysprosium-doped CdO nanoparticles were prepared by sonochernical method in aqueous media and characterized with X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-Vis diffuse reflectance, spectrum, and photoluminescence spectra. The results of XRD indicated that the obtained CdO : Dy3+ nanoparticles were well crystallized with a cubic phase. The TEM image illustrated that the CdO : Dy3+ nanoparticles were spherical with an average size around 40 nm. Under irradiation of UV light, the emission spectrum of CdO : Dy3+ nanoparticles exhibited alongwith the host emission, the characteristic line emissions arising from the 4 F-9/2 -> H-6(J) (J = 13/2, 15/2) transitions of the DY3+ ions, with the dominating emission centered at similar to 580 nm. The optimum doping concentration for CdO : Dy3+ nanoparticles was determined to be 3 mol%.
