Synthesis and characteristics of Li-doped ZnO powders for p-type ZnO

Li-doped zinc oxide (ZnO) powders were synthesized by combustion synthesis method using glycine, urea and metal nitrate as the starting materials. The structural and morphological properties of Li-doped ZnO powders were characterized by TG-DSC, XRD and TEM. Results show that as-prepared powders are crystalline in nature and their average sizes are 0.2-0.4 mu m. XPS and XRD results clearly show that Li element had doped into ZnO crystal lattice, which is benefit for fabrication of p-type ZnO films. (C) 2010 Elsevier B.V. All rights reserved.
