Rare earth metal seed Tb was employed for the growth of GaNnanorods. GaNnanorods were synthesized successfully through ammoniating Ga2O3/Tb films sputtered on Si(111) substrates. X-ray diffraction results indicated that the nanorods were hexa nal GaN. Observations using scanning electron microscopy and high-resolution transmission electron microscopy showed that GaN was of single-crystal nanorod structure, with diameter 50-150 nm and length about 10 μm. Photoluminescence spectrum showed a strong UV emission peak at 368.6 nm, indicating that the products possess od luminescent characteristics. The growth mechanismof GaN nanorods was also discussed.
