✦ Synopsis

A novel rare earth metal seed Tb was employed as the catalyst to grow GaN nanorods.

Large-scale GaN nanorods were synthesized successfully through ammoniating Ga 2 O 3 /Tb films sputtered on Si(1 1 1) substrates. Studies by X-ray diffraction indicate that the nanorods are hexagonal GaN. Observations by scanning electron microscopy and high-resolution transmission electron microscopy show that GaN is of single-crystal nanorod structure.

Photoluminescence spectrum shows the products possess good luminescent properties.

The growth mechanism of GaN nanorods is also discussed.
