摘要：
CdWO4 nanorods with wolframite structure were synthesized in the presence of the surfactant SDBS by a hydrothermal method, and characterized by a variety of techniques. The obtained products are CdWO4 nanorods with length of 0.8-2.5 mu m and width of 50-250 nm. The surfactant SDBS plays a key role in the formation of the CdWO4 nanorods. The pH value impacts on crystallinity of the products. The PL properties of the CdWO4 nanorods prepared under different conditions were studied. The intensity of the PL emissions of the samples increases with crystallinity and aspect ratio of the CdWO4 nanorods.
