Abstract: Uniform Eu3+ doped CdWO4 nanorods 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 CdWO4 nanorods 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 WO4 2- and red emission from Eu3+ can be tuned through doping Eu3+ ions into the CdWO4 nanorods and thus altering the energy transfer between WO4 2- 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.
