GAO, Bin; FAN, Huiqing  and  ZHANG, Xiaojun. Hydrothermal synthesis of CdWO₄ nanorods and their photoluminescence properties. S.Afr.j.chem. (Online) [online]. 2012, vol.65, pp.125-130. ISSN 1996-840X.

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 µm 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.

Keywords : CdWO₄ nanorods; photoluminescence; hydrothermal method.
