摘要：

Pb2+ doped zinc-oxide nanodisks have been grown through a facile solvothermal method. The nanodisks have perfect hexagonal shape with about 1 mu m diagonal and 100 nm in thickness. The existence of Pb2+ is vital to the formation of the disk morphology. Room temperature photoluminescence measurements show two photoluminescence peaks centered at 518 and 648 nm. The mechanism of the nanodisk growth is also discussed. (c) 2006 Elsevier Ltd. All rights reserved.
