Integration of luminescent rare earth ions and iridescence into a zirconium oxide photonic material is attractive for the design of new optical devices. The free-standing chiral nematic mesoporous films of ZrO2:Eu(3+) are assembled by a hard-templating approach using nanocrystalline cellulose-templated silica. The ZrO2:Eu(3+) films show tunable optical properties. The chiral nematic structured ZrO2:Eu(3+) exhibits selective suppression of the spontaneous emission of Eu(3+) and the capability to modulate the lifetime of luminescent Eu(3+).
将发光稀土离子与虹彩集成到氧化锆光子材料中，对于新型光学器件的设计具有吸引力。ZrO2:Eu(3+)的独立手性向列型介孔薄膜通过使用纳米晶纤维素模板化二氧化硅的硬模板法组装而成。ZrO2:Eu(3+)薄膜表现出可调谐的光学性质。手性向列结构的ZrO2:Eu(3+)表现出对Eu(3+)自发发射的选择性抑制以及调节发光Eu(3+)寿命的能力。
