摘要
在研究不同配比的发光粉基质材料铝酸锶的基础上 ,对Sr0 .95Eu0 .0 2 5Dy0 .0 2 5O·Al2 0 3 和 4(Sr0 .95Eu0 .0 2 5Dy0 .0 2 5O)·7Al2 O3 进行发射光谱的测试和SEM分析 ,得出Eu2 + 处在不同晶格结构中发射光谱不同的结论 .
Based on the studying on strontium aluminate compound-matrix materials of luminescent powders with different compositions, the emission spectra of phosphor Sr 0.95 Eu 0.025 Dy 0.025 O·AL 2O 3 and 4(Sr 0.95 Eu 0.025 Dy 0.025 O)·7AL 2O 3 were determined, and their SEM micrograph were observed. The conclusion is the luminescent spectra of Eu 2+ which lies in different lattice structure are different.
