BaMgAl10O17:Eu2+ (BAM) phosphor particles were prepared by sol-gel processes. The effect of the firing temperature and the Eu2+ concentration on the distribution of Eu2+ among different sites was firstly investigated through the changes of excitation spectra with changing firing temperature and Eu2+ concentration. The mechanism underlying was elucidated. The stability of BAM could be improved by increasing the firing temperature and Eu2+ concentration. (c) 2006 Elsevier B.V. All rights reserved.
