Growth of Self-Catalyzed ZnO Heterostructures Using Thermal Chemical Vapor Deposition Method

Article Preview

Abstract:

ZnO heterostructures have been successfully synthesized using thermal chemical vapor deposition method. Zinc powder and oxygen were used as the starting materials, while argon gas was supplied as the carrier gas. Different types of nanostructures were deposited on layer-by-layer ZnO seeded catalyst; which its structures depended on the position of the substrates during the deposition process. Substrates at position C which is located 3 cm from the source shows uniformly distributed ZnO nanorods. XRD pattern also shows that sample C shows (0 0 2) diffraction peak. PL spectra indicates that the ZnO have two peaks, which is UV peak centered at 380 nm and visible peak centered at about 550 nm.
