FIG. 1.

(a) A typical cross-sectional SEM image of ZnO:Cu nanoneedles (sample N1). (b) TEM image of a ZnO:Cu nanoneedle and its corresponding high resolution TEM image is shown in (c). (d) Comparison of the SAED patterns of ZnO:Cu nanoneedles with the simulated patterns of ZnO. Some weak diffraction spots related to CuO were detected.
