Abstract
The influence of concentration and temperature on the luminescence pro perties of the Eu3+ activated X-1-Y2SiO5 are investigated for the firs t time. For high Eu3+ concentration, a cross relaxation process betwee n Eu3+ ions results in the quenching of D-5(1) emission. At low temper ature and high concentration, the excitation transfer between Eu3+ ion s in the two sites enables the fluorescence of site 2 disappears entir ely. In addition, the samples showed some interesting phenomenon relat ed to size effect. (C) 1998 Elsevier Science B.V. All rights reserved.
