| Summary: | 碩士 === 逢甲大學 === 光電學系 === 106 === In this study, we demonstrated a composited photonic crystal hydrogel film with three dimensional colloidal array use to solvent sensors, that was fabricated by infiltrating the gaps of colloidal array with hydrogel aqueous solution,by UV curing.The hydrogel photonic crystal film sensor was immersed in alcohols, that the experimental result exhibited the red-shift of the reflection light, because of the lattice constant and effective refractive index was increased.The color of the composited photonic crystal hydrogel films can be turned over the visible light （439−637 nm） by changing concentration of alcohols solution over. The redshift of this sensor had linear response to the concentration of alcohols solution, while its structural color changed from blue to green visually. We used a composited photonic crystal sensing film combination with white LEDs as an alcohol sensing module. This study promising potential as an on-site monitoring sensor for alcohols.
