The high-quality phosphorus-doped ZnO nanocombs were synthesized by the simple chemical vapor deposition method without use of any catalyst. The images of field-emission scanning electron microscopy show that the phosphorus-doped ZnO nanocombs have a uniform length of 8μm with the diameter of 70nm and the cusp of the teeth of 20nm. The measurement results of selected-area electron diffraction pattern indicate that the phosphorus-doped ZnO nanocombs are single crystalline structure. The phosphorus related acceptor emission was observed in the photoluminescence spectra of phosphorus-doped ZnO nanocombs at 11K. The acceptor binding energy is estimated to be ∼127meV. ► The high-quality phosphorus-doped ZnO nanocombs were synthesized by the CVD method. ► The phosphorus related acceptor emission was observed in the PL spectra at 11K. ► The acceptor binding energy is estimated to be∼127meV.
