文摘

Two-dimensional double-layer micro/nanostructured ZnO disks were fabricated in large quantity by a facile solution route at 50 °C within a short reaction time using citrate as crystal growth modifiers. The disks are round-shaped and double-layer nanostructured, about 2 μm in diameter and 400 nm in thickness, which is a new member of the nanostructured ZnO family. Polar-field-induced growth is proposed for the formation of the double-layer ZnO disks. Photoluminescence measurements indicate that there is a strong violet emission in such disks, which is expected to find applications in next generation nanostructured optoelectronic devices.
