手性向列介孔氧化钇薄膜对于新型光学器件的设计具有吸引力。 Y2O3:Eu3+ 的独立手性向列介孔薄膜是使用纳米晶纤维素模板二氧化硅通过硬模板方法组装而成。具有可调光学特性的Y2O3:Eu3+薄膜能够调制Eu3+离子的自发发射并表现出有趣的光致发光特性。
Chiral nematic mesoporous yttrium oxide films are attractive for the design of new optical devices. The free-standing chiral nematic mesoporous films of Y2O3:Eu3+ are assembled using a hard-templating method using nanocrystalline cellulose-templated silica. The Y2O3:Eu3+ films with tunable optical properties are capable of modulating the spontaneous emission of Eu3+ ions and exhibit interesting photoluminescence properties.
