以正硅酸乙酯、CaO、Eu2 O3和Dy2 O3为原料，采用溶胶-凝胶法制备了硅酸盐蓄能发光材料CaSiO3：Eu2＋，Dy3＋，并利用X射线衍射、荧光光谱等分析手段研究了蓄能发光材料的晶格结构、光谱特性和影响材料发光性能的工艺因素。结果表明，灼烧温度对样品晶格结构及发光性能有重要影响。当温度低于1300℃时，样品晶格结构发育不完善，温度高于1400℃时，样品容易产生烧结现象。Eu2＋作为发光中心，其浓度对样品发光性能有重要影响，当Eu2＋掺杂的物质的量为0．005 mol时，样品发光强度最大，此时，样品的发射光谱是一个峰值位于544 nm的不对称宽带发射。

CaSiO3 :Eu2+ ,Dy3+ silicates storage luminescent materials were prepared by sol-gel method that use ethyl silicate , CaO ,Eu2 O3 ,Dy2 O3 as the starting materials . The lattice structure and spectroscopic properties of storage luminescent materials and the influencing factors on luminescence properties were studied by X-ray diffraction ,fluorescence spectrum and other analytical tools . The results indicate that the calcination temperature have great influence on lattice structure and luminescence properties of sample .When the temperature is below 1 300 ℃ ,crystal lattice structure of sample is imperfect . The temperature higher than 1 400 ℃ ,the sample is prone to produce sintering phenomenon .Eu2+ as luminescent centers and its concentration have great influence on luminescence properties of samples .When the Eu2+ concentration was 0 .005 mol ,the luminous intensity of sample reached the maximum .In this case ,the emission spectrum of the sample was an asymmetrical transmission that the peak located in 544 nm .
