PEG Assisted Hydrothermal Synthesis of ZnO Nanorods |
| |
| Abstract: | ZnO nanorods have been synthesized by a PEG assisted hydrothermal method. XRD shows that the product is hexangular ZnO with high crystallization. PL spectrum suggests that the product after annealing has good optic emission property. TEM and SAED were used to investigate the microstructure and growth mechanism of ZnO nanorods. The effects of concentration of NaOH and the synthesis time on the product were also studied. |
