Growth of hexagonal prism ZnO nanorods on Zn substrates by hydrothermal method and their photoluminescence

Growth of hexagonal prism ZnO nanorods on Zn substrates by hydrothermal method and their photoluminescence

Hexagonal prism ZnO nanorods were successfully grown on Zn substrates by the 120 °C and 24 h hydrothermal reaction of the solutions with pH of 9-12. Results from XRD, SEM, TEM, SAED and HRTEM showed that the as-synthesized products were wurtzite ZnO with the shape of hexagonal prism nanorods grown a...
