英文摘要	Nanosized Y2O3:Eu was synthesized by using a solution-combustion method. The samples were characterized by x-ray diffraction, extended x-ray absorption fine structure (EXAFS), and photoluminescence spectroscopy. Our EXAFS result showed that the local environments surrounding both Y and Eu atoms had obviously changed when the particle size was smaller than 10 nm. The coordination number and the bond length of Y (Eu)-O shell increased and the disorder became larger. This change also produced an emission peak and the charge-transfer band showed an unusual redshift as the particle size decreased. The luminescence properties can be explained by use of the EXAFS results. (C) 2002 American Institute of Physics.
