We report a method to grow structurally-controlled CdSe nanostructures by adopting Bi-mixed CdSe powder source to a catalyst-assisted chemical vapor deposition. Using this method, we synthesized Bi-doped CdSe nanocrystals with different shapes, such as nanocrystal film, nano-bumpy film, nanobelts, and nanowires. We fabricated a photodetector and a field-effect device using Bi-doped CdSe nanowires with high responsivity to white light. These results will offer a wide range of application possibilities in optoelectronic devices using CdSe nanostructures.
