Synthesis of Luminous Material of SrO-TiO2-SiO2:Eu3+,Bi3+by Sol-Gel Method
【摘要】 用Sol-Gel法合成了SrO-TiO2-SiO2为基质、稀土Eu3+激活的发光材料;研究了材料的合成条件,测试了样品的激发光谱、发射光谱、X-ray衍射光谱等;用TGA-DTA分析了样品合成时的反应行为;获得了合成样品的最佳组成及最佳实验条件。
【Abstract】 The luminous materials of SrO-TiO2-SiO2-SiO2:Eu3+,Bi3 are synthesized by Sol-gel m- ethod. The condition of synthesis is studied. It is found that the compound with the formula 2SrO -4(TiO2,SiO2):0.12Eu3+, 0.005Bi3+ gives .the strongest fluorescence. The excitation spectra, emission spectra and X-ray power diffraction pattern of the phosphor are also given.
