中文摘要	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+.
