Eu3+激活的SrO-BaO-SiO2发光材料的合成和特性研究
摘要:
(Sr,Ba)SiO3:Eu3+是以SrCO3、BaCO3、H2SiO3、Li2CO3、Eu2(C2O4)3为原料,经高温烧结而成。合成发光材料过程中,用正交试验法进行实验条件的探索。得到了发光材料的最佳组成为:(Sr0.8Ba0.2)0.95Eu0.025Li0.025SiO3或Si0.95Eu0.025Li0.025SiO3。最佳实验条件为:灼烧温度1150℃,灼烧时间3小时。通过X-射线粉末衍射谱、激光荧光光谱、发光光谱和激发光谱研究了发光材料的结构和发光特性。

SYNTHESIS AND PROPERTY OF Eu3+ ION ACTIVATED SrO-BaO-SiO2 PHOSPHORS
Abstract:
(Sr,Ba)SiO3: Eu3+ was synthesized at high temperature using SrCO3,BaCO3, H2SiO3, Li2CO3 and Eu2(C2O4)3 of A.R.grade. The optical synthesis conditions were achieved through orthogonal design, i.e. 1150℃ and 3 hr. The products with constitution of (Sr0.8Ba0.2)0.95Eu0.025Li0.025SiO3 or Sr0.95Eu0.025Li0.25SiO3 show the greatest intensity of illumination. The property of the product has been studied by means of x-ray powder diffraction, laser fluorescence and illuminant spectroscopy.
