Hydrothermal synthesis and optical properties of Pb2+ doped ZnO nanorods

Single-crystalline Pb2+ doped ZnO nanorods were synthesized by a hydrothermal method in the presence of cetyltrimethyl ammonium bromide (CTAB). The obtained Pb2+ doped ZnO nanorods were in diameters of similar to 150 nm and in lengths of similar to 3 mu m. The nanorods grow along the [0110] direction. The Pb2+ doped ZnO nanorods show violet and blue emission bands centered at 415, 438 and 467 nn, respectively. The possible growth mechanism of the Pb2+ doped ZnO nanorods was also discussed.
