Powder samples of SrY{sub 2(1{minus}x)}O{sub 4}:Eu{sub 2x} were prepared at 1,000 C by the combustion method. The emission spectrum of SrY{sub 2}O{sub 4}:Eu{sup 3+} showed two kinds of Eu{sup 3+} emissions, which could be assigned to Eu{sup 3+} ions in the Sr site and the Y site. Reducing SrY{sub 2}O{sub 4}:Eu brought a broad band emission around 470 nm, which could be attributed to crystal defects introduced by the reduction. The energy transfer from defects to Eu{sup 3+} ions was observed to be more effective to the Sr site than to the Y site.
