Uniform Eu3+doped CdWO4nanorods were prepared via a simple hydrothermal method and characterized by X-ray diffraction, transmission electron microscopy, photoluminescence (PL) spectroscopy and PL lifetime measurements. The results indicate that the obtained Eu3+doped CdWO4nanorods have monoclinic phase structure, and the phase structure can be retained at Eu3+doping concentrations of 0.4-4.0%. The diameter of nanorods decreases from 27 to 15 nm with an increase in the doping concentrations, and the morphology becomes irregular at the Eu3+doping concentration of 6.5%. Under the excitation of ultraviolet light, the relative intensities of blue-green emission ascribed to WO42-and red emission from Eu3+can be tuned through doping Eu3+ions into the CdWO4nanorods and thus altering the energy transfer between WO42-and Eu3+. Hence, the multi-color luminescence in the same host at a single excited wavelength can be realized simply by altering the doping concentration of Eu3+. These luminescent nanomaterials may have potential applications in displays, light sources, bio-imaging and so on. This journal is
