FESEM image of as-prepared ZnO nanorods and PbS QD-coated ZnO nanorod arrays with different CBD cycles. (a) ZnO nanorods, (b) ZnO nanorods coated by PbS QDs with 2 CBD cycles, (c) ZnO nanorods coated by PbS QDs with 4 CBD cycles, and (d) ZnO nanorods coated by PbS QDs with 6 CBD cycles. The scale bar is 200 nm.
