Abstract

In this paper, ZnGa(2)O(4) hierarchical nanostructures with comb-like morphology are fabricated by a simple two-step chemical vapor deposition (CVD) method: first, the Ga(2)O(3) nanowires were synthesized and employed as templates for the growth of ZnGa(2)O(4) nanocombs; then, the as-prepared Ga(2)O(3) nanowires were reacted with ZnO vapor to form ZnGa(2)O(4) nanocombs. Before the reaction, the Au nanoparticles were deposited on the surfaces of Ga(2)O(3) nanowires and used as catalysts to control the teeth growth of ZnGa(2)O(4) nanocombs. The as-prepared ZnGa(2)O(4) nanocombs were highly crystallized with cubic spinel structure. From the photoluminescence (PL) spectrum, a broad band emission in the visible light region was observed of as-prepared ZnGa(2)O(4) nanocombs, which make it promising application as an optical material.
