摘要：

The dandelion-like ZnO nanostructures on silicon substrate were successfully synthesized by a simple thermal evaporation method using Zn and zinc acetate dihydrate as the source materials. Detailed structural characterizations confirm the single-crystalline with wurtzite hexagonal phase and exhibit that they are grown along the [0001] direction. Photoluminescence exhibits a weak UV emission at similar to 386 nm and a strong green emission at similar to 495 nm with 325 nm excitation. Field emission measurements demonstrate that the dandelion-like nanostructures possess good performance with a turn-on field of similar to 1.67 V/mu m and a threshold field of similar to 7.22 V/mu m.
