Single-crystalline CdWO4 nanorods and nanofibers are selectively prepared based on hydrothermal treatment with cetyltrimethylammonium bromide (CTAB) as capping molecule and ordinary inorganic reactant as precursors through exactly controlling the pre-treated condition. With almost uniform breadth and pointed ends, the obtained short nanorods show a relatively thick nature along [010] direction and self-assemble to an ordered structure with (001) and (010) faces, respectively, while the as prepared nanofibers are flexible and vertically self-assemble to form woven network. The mechanism of selective preparation and self-assembly was also discussed. Both obtained nanorods and nanofibers display a very strong blue-green luminescence property at room temperature.
