摘要：

Preparation and morphology of nanocrystalline and nanoporous ceramics composed of a network of alumina and zinc aluminate doped with To ions are reported. The pore size distributions are determined by nitrogen adsorption at 77 K. The emission spectra and lifetimes of Tb3+ ions were measured. The effect of thermal conditions of preparation on emission properties was investigated. It is concluded that with increasing thermal heating the sizes of nanoparticles increase leading to the cluster formation of Tb3+ ions. (C) 2001 Elsevier Science B.V. All rights reserved.
