Abstract
Tb3+-doped zinc oxide nanocrystals with a hexagonal wurzite structure were successfully prepared by reaction between Zn-O-Tb precursors and LiOH in et hanol. Good incorporation of Tb3+ in ZnO nanocrystals is proved by XRD, FTI R, PL and PLE measurements. The presence of acetate complexes to zinc atoms on particle surfaces is disclosed by FTIR results. Emission from both Tb3 ions and surface states in ZnO matrix, as well as their correlation were o bserved. The luminescence mechanism is discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
