Abstract :
Wurtzite InN nanobelts have been synthesized in bulk quantities by means of in situ nitriding indium oxide powders in ammonia flux, with a high yield, high purity and good reproducibility. As-synthesized InN nanobelts have typical widths of 1–5 μm, thickness of 40–50 nm and lengths of tens to hundreds of microns imaged by scanning electron microscopy. Transmission electron microscopy reveals that the synthesized InN nanobelts are single crystalline in [0 0 0 1] orientation and preferentially enclosed by top surfaces ± ( 0 1 1 ¯ 0 ) /side surfaces ± ( 2 1 ¯ 1 ¯ 0 ) . Photoluminescence spectrum of InN nanobelts at room temperature shows a strong emission peak centered at 704 nm (1.76 eV).
