Large-sized (ca. 40 nm) mesoporous Er2O3 thin films are synthesized by using a triblock copolymer poly(styrene-b-2-vinyl pyridine-b-ethylene oxide) (PS-b-P2VP-b-PEO) as a pore directing agent. Each block makes different contributions and the molar ratio of PVP/Er(3+) is crucial to guide the resultant mesoporous structure. An easy and general method is proposed and used to prepare a series of mesoporous rare-earth oxide (Sm2O3, Dy2O3, Tb2O3, Ho2O3, Yb2O3, and Lu2O3) thin films with potential uses in electronics and optical devices.
通过使用三嵌段共聚物聚（苯乙烯 - b - 2 - 乙烯基吡啶 - b - 环氧乙烷）（PS - b - P2VP - b - PEO）作为孔导向剂，合成了大尺寸（约40 nm）的介孔Er2O3薄膜。每个嵌段发挥不同作用，PVP/Er(3+)的摩尔比对于引导所得介孔结构至关重要。提出并采用了一种简便通用的方法来制备一系列介孔稀土氧化物（Sm2O3、Dy2O3、Tb2O3、Ho2O3、Yb2O3和Lu2O3）薄膜，这些薄膜在电子和光学器件中具有潜在用途。
