摘要：

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.
