Abstract In the present study cerium substitution effects in the sol-gel derived yttrium iron garnet (Ce:Y3Fe5O12, Ce:YIG) have been investigated. To avoid formation of CeO2 as side phase the samples were prepared under different conditions. Synthesis of Ce:YIG in the reducing atmosphere, however, showed the formation of perovskite YFeO3 as dominant phase. Mixed-metal cerium substituted yttrium aluminium iron garnets (Ce:Y3Al5-xFexO12, Ce:YIAG) were synthesized in the form of bulk and coating. Single phase Y2.925Ce0.075Al5-xFexO12 (x = 1, 2, 3, and 4) were successfully synthesized using the same sol-gel processing route. The garnet thin films with composition of Y2.925Ce0.075Al1Fe4O12 were fabricated on a quartz substrate by dip-coating technique. The phase purity and structural features of obtained powders and thin films were evaluated using X-ray diffraction (XRD) analysis. The surface composition was determined by X-ray photoelectron spectroscopy (XPS). The morphology of synthesis products was investigated by scanning electron microscopy (SEM).

铈掺杂和铈铝共掺杂对 Y3Fe5O12 (YIG) 溶胶-凝胶加工的影响：块状和薄膜

摘要 在本研究中，已经研究了溶胶-凝胶衍生的钇铁石榴石 (Ce:Y3Fe5O12, Ce:YIG) 中铈的取代效应。为了避免形成 CeO2 作为副相，在不同条件下制备样品。然而，在还原气氛中合成 Ce:YIG 显示钙钛矿 YFeO3 作为主要相的形成。以块体和涂层的形式合成了混合金属铈取代的钇铝铁石榴石（Ce：Y3Al5-xFexO12，Ce：YIAG）。使用相同的溶胶-凝胶工艺路线成功合成了单相 Y2.925Ce0.075Al5-xFexO12（x = 1、2、3 和 4）。通过浸涂技术在石英衬底上制备了成分为 Y2.925Ce0.075Al1Fe4O12 的石榴石薄膜。使用 X 射线衍射 (XRD) 分析评估所得粉末和薄膜的相纯度和结构特征。通过 X 射线光电子能谱 (XPS) 确定表面组成。通过扫描电子显微镜（SEM）研究合成产物的形态。
