摘　　要：以黄磷炉渣为原料,采用酸浸的方法得到SiO_(2)基体材料,将稀土配合物铈/邻苯二甲酸氢钾掺杂到通过醇酯法改性的SiO_(2)基体材料中,得到SiO_(2)∶Ce^(3+)荧光材料。通过X射线衍射仪、扫描电子显微镜、傅里叶变换红外光谱仪和荧光分光光度计对荧光材料进行表征。结果表明:合成的SiO_(2)∶Ce^(3+)荧光材料为无定型结构,形貌为块状颗粒,颗粒表面附着了大量的小颗粒;在检测波长为404nm时得到有效激发,激发主峰为213nm,激发峰强度达到9866;发射主峰为404nm,发射峰强度达到4253,荧光材料发光性能良好。SiO_(2) matrix material was obtained by acid leaching method using yellow phosphorus slag as raw material,and the rare earth complex cerium/potassium hydrogen phthalate was doped into the SiO_(2) matrix material modified by alcohol ester method to obtain SiO_(2)∶Ce^(3+)fluorescent material.The fluorescence material was characterized by X-ray diffractometer,scanning electron microscope,Fourier transform infrared spectrometer and fluorescence spectrophotometer.The results showed that the synthesized SiO_(2)∶Ce^(3+)fluorescent material had an amorphous structure,and the morphology was massive particles with a large number of small particles attached to the surface of the particles.When the detection wavelength was 404nm,the fluorescent material could be effectively excited,with an excitation peak at 213nm and an excitation peak intensity of 9866.The emission peak was observed at 404nm,with an emission peak intensity of 4253,which indicated that the luminescence performance of the fluorescent material was good.
