中文摘要	the nanocrystalline sry(2)o(4):eu3+ was prepared by a poly(vinyl alcohol) (pva)+glycine-assist combustion method. the results of x-ray diffraction indicate that the resulting sry(2)o(4):eu3+ nanocrystals have much broader and less intense peaks compared with those in bulk material. the charge-transfer bands in sry(2)o(4):eu3+ nanocrystals shift to higher energies in contrast to those in bulk material. the spectral results revealed that in bulk sry2o4: eu3+ the eu3+ ions occupied three nonequivalent sites, with one at the sr site: one at the y(1) site and another at the y(2) site, while in nanocrystalline sry2o4: eu3+, the eu3+ ions occupied only two nonequivalent sites; one at the y(1) site and the other at the y(2) site. finally, by theoretical calculation and analysis, the analyzed results are in reasonable agreement with our experimental results.
