In this work, three samples were synthesized; SnO 2 nanoparticles, ZnO nanorods and ZnO/SnO 2 core–shell nanorods. The preparation of the ZnO/SnO 2 composite included two steps, the first was to spin ZnO thin film as a seed layer. The second step is to grow ZnO/SnO 2 to produce core–shell nanorod de...
