锆、钛掺杂改性铝酸锶长余辉发光材料性能的研究

Study on Zr^(4+),Ti^(4+) Doped SrAl_2O_4: Eu^(2+),Dy^(3+) for Improving its Luminescent Properties

应用燃烧法合成了锆、钛掺杂SrAl2O4:Eu2+,Dy3+黄绿色长余辉发光材料,并对材料发光性能进行测试分析.结果表明,锆、钛掺杂能明显改善铝酸锶样品的发光性能.锆、钛的最佳掺杂摩尔比分别为6%和3.75%.

Yellow-green long afterglow phosphors SrM4＋0.75xAl2-xO4：Eu2＋,Dy3＋（M4＋=Zr4＋,Ti4＋） were synthesized by the combustion method.Their photoluminescence were investigated.The results showed that the dopants of Zr4＋ and Ti4＋ can improve the luminescent properties of phosphors.The best dopant amounts of Zr4＋ and Ti4＋ are 6 % and 3.75 %,respectively.
