Chiral nematic mesoporous films of Y2O3:Eu3+ with tunable optical properties and modulated photoluminescence

Abstract

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.
