Abstract

We produced gallium oxide (Ga2O3) nanomaterials with various widths on chromium (Cr) substrates by the thermal evaporation of GaN powders. We characterized the samples using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy and photoluminescence spectroscopy. The results showed that the products consisted of belt-like Ga2O3 nanomaterials, which had monoclinic structures. The photoluminescence spectrum showed a blue light emission.
