【摘要】 采用溶胶-凝胶法与沉淀法相结合的方法在600℃退火处理后,合成了BaSO₄-SiO₂∶Eu³⁺及BaSO₄∶Eu³⁺发光材料.通过XRD、IR、荧光光谱对材料的物相及发光性能进行了表征和分析.实验考察了SO₄^2-和正硅酸乙酯（TEOS）掺杂量对材料荧光性能的影响,样品出现了3个发射峰,分别为577 nm、613 nm和715 nm处.研究结果表明,SO₄^2-和TEOS的掺杂量基本不影响样品发射峰的位置,但荧光强度会随着含量的增加而增强.更多还原

【Abstract】 Luminescent materials BaSO₄-SiO₂∶Eu³⁺and BaSO₄∶Eu³⁺were prepared by sol-gel method and precipitation method.XRD,IR and luminescence spectra were used to characterize the phase and luminescence properties of the materials.The effects of doping amount of SO₄^2-and TEOS on the fluorescence properties of the materials were investigated.There were three emission peaks at 577 nm,613 nm and 715 nm.The results show that the content of SO₄^2-and TEOS have no effect on the positions of emission peaks,but the fluorescence intensity will increase with the increase of content.更多还原
