Synthesis of blue-light-emitting ZnGa2O4nanowires using chemical vapor deposition

Abstract

A high-density array of vertically aligned ZnGa₂O₄ nanowires has been synthesized on Si substrates via CVD of ZnO–Ga at 1000 °C consisting of a single-crystalline cubic spinel structure grown in a [111] direction and exhibiting strong photoluminescence and cathodoluminescence in the blue wavelength region.
