在无机钙钛矿材料的胶体合成中，油酸铯（CsOL）是最常用的Cs前体。 然而，尽管在文献中普遍使用了CsOL，但已观察到CsOL在室温下不溶，并导致CsPbX 3的结果出乎意料地不一致纳米晶体的合成，取决于前体衍生自的Cs盐。 oleate是一种十八碳链长的脂肪酸酯。 它是一种无色至微黄色的液体，具有脂肪酸酯的特性，如可溶于有机溶剂但不溶于水。 In the colloidal synthesis of inorganic perovskite materials, cesium oleate (csol) is the most commonly used cs precursor

Yet, despite its ubiquitous use in literature, csol has been observed to b. 步骤s1中，将铯前驱体溶液热注入到溴化锡前驱体溶液中，以反应生成钙钛矿晶体，具体为：将溴化锡前驱体溶液于氮气环境下升温至230℃，以玻璃针筒注入0.4ml油酸铯前驱物 (cs-oleate)，并待反应15分钟后，进行步骤s2，迅速将三颈瓶冰水浴冷却至20℃。 Pdf | in the colloidal synthesis of inorganic perovskite materials, cesium oleate (csol) is the most commonly used cs precursor.

作为油酸衍生物，oleate由油酸阴离子（C17H33COO⁻）与金属阳离子（如钠、钾）结合成盐，或与醇类（如甲醇、乙醇）结合成酯，广泛存在于动植物油脂中。 常见类型包括油酸钠、油酸甲酯等，应用于化妆品乳化剂、工业润滑剂及食品添加剂等领域。
