Synthesis and Characterization of Flower-shaped ZnO Nanostructures by the Solution Process |
| 초록 |
Synthesis of flower-shaped ZnO nanostructures ZnO nanorods was achieved by the simple solution process using 0.2M zinc acetate dihydrate and 1M sodium hydroxide in 100ml diionized water at very low temperature about ~90°C in 30 minutes refluxing time. Detailed morphological and optical characterizations demonstrate that the synthesized products are single crystalline with the wurtzite hexagonal phase and grown along the [0001] direction. The composition of as synthesized white powder was analyzed by the IR spectroscopy. Where a standard peak of zinc oxide was observed at 523 cm-1. Raman scattering exhibits a sharp and strong E2 mode at 437 cm-1 which further confirms the crystallinity and wurtzite hexagonal phase for the grown nanostructures. Room-temperature photoluminescence (PL) demonstrate a strong and dominated peak at 381 nm with a suppressed and broad green peak at 515 nm, suggests that the flower-shaped ZnO nanostructures have good optical properties with very less structural defects. |
