Mesoporous bragg stack color tunable sensors.

摘要: Herein we report a novel self-assembly synthesis, structural and optical characterization of mesoporous Bragg stacks (MBS) composed spin-coated multilayer TiO2 SiO2. Investigation the response MBS to infiltration alcohols alkanes into its pores reveals better sensitivity selectivity than conventional reflectors. Furthermore, demonstrate that chemical sensing ability can be tuned via layer thickness, composition surface properties.
