This unique class of nanomaterials has shown many unprecedented properties(big surface area, high surface effect, physical and chemical activities) and is thus being explored for numerous promising applications. In this review, a brief introduction of ultrathin Ln_2O_3 nanomaterials was given and their unique advantages were highlighted. Then, the typical synthetic methodologies were summarized and compared(thermal decomposition, solvothermal, soft template, co-precipition and microwave etc.). Due to the high surface effect, some promising applications of ultrathin Ln_2O_3 nanomaterials, such as drug delivery and catalysis of CO oxidation, were reviewed. Finally, on the basis of current achievements on ultrathin Ln_2O_3 nanomaterials, personal perspectives and challenges on future research directions were proposed. 关 键 词：稀土氧化物 纳米材料 合成方法 超薄 应用 特性 表面效应 材料科学
