The Tb3+-doped zinc salicylate, Zn(HOC6H4CO2)(2):Tb, and the zinc monosalic
ylate, alpha- and beta-Zn(OC6H4CO2): Tb, are synthesized by rheological pha
se reaction and thermal decomposition. alpha-Zn(OC6H4CO2): Tb has very stro
ng green emission of Tb3+ under excitation with UV light. The excitation an
d emission spectra are investigated. The relationship between the luminesce
nce properties and crystal structures, and the energy transfer mechanism ar
e discussed. (C) 1999 Elsevier Science S.A. All rights reserved.
