摘要:
以硝酸盐和尿素为基质,采用一次燃烧法在较低炉温(600~620℃)下合成了SrAl2O4:Eu2+,Dy3+长余辉发光材料.通过对比实验,研究了原料的用量对产物合成及性能的影响.实验结果表明,在n(尿素):n(硝酸盐)=12∶1,硼酸摩尔分数为0.10%~0.12%,Eu2O3为0.2%,Dy2O3为0.4%时,制备的SrAl2O4: Eu2+,Dy3+具有好的余辉性能.
Abstract:
SrAl2O4:Eu2+,Dy3+ long afterglow phosphor were successfully synthesized at lower temperature (600~620℃),using nitrate and carbamide as starting materials. The effect of dosages of reactants on the synthesis and properties of production were studied by comparative test. The results showed that SrAl2O4: Eu2+,Dy3+was prepared with excellent spectral behaviors under the conditions as follows: the molar ratio of carbamide to nitrate was 12∶1, the dosages of boric acid, europium oxide, dysprosium oxide were 0.10%~0.12%, 0.2%, 0.4%, respectively.
