【 摘 要 】

In this study, an aqueous sol-gel synthesis method was applied for the preparation of strontium aluminate (Sr₃Al₂O₆ and SrAl₁₂O₁₉) ceramics. The structural properties of these compounds were investigated by X-ray powder diffraction analysis. The obtained data were analysed employing Rietveld method. Optical properties of sol-gel derived cerium-doped strontium aluminates showed emission maxima at 480 nm and 317 nm for Sr₃Al₂O₆:Ce and SrAl₁₂O₁₉:Ce, respectively.
