摘要：

Photoluminescence properties of Eu3+-doped GdAlO3 and LaAlO3 phosphors prepared by sol-gel method have been investigated by the site-selective laser spectroscopy along with the decay time measurements at room temperature. The site-selective excitation spectra showed one F-7(0) -> D-5(0) transition line in GdAlO3:Eu3+ and three F-7(0) -> D-5(0) transition lines in LaAlO3:Eu3+, indicating that there was only one crystallographic site for Eu3+ in GdAlO3 and three crystallographic sites for Eu3+ in LaAlO3. The result of LaAlO3 was not in agreement with its crystal structure. The stark energy levels for Eu3+ at different sites were characterized and discussed by site-selective emission spectra arose from D-5(0) level of Eu3+. (C) 2012 Elsevier B.V. All rights reserved.
