Photonic Crystal Sensors for the Composition of Liquids Based on Films with the Structure of Inverse Opal

The possibility of using films of inverse opals made of a photoresist as sensors for the determination of the concentration of alcohols in water is studied. The analytical signal is the spectral position of the photonic stop band. The signal linearly grows with the increase in the concentration of e...

Zusammenfassung:The possibility of using films of inverse opals made of a photoresist as sensors for the determination of the concentration of alcohols in water is studied. The analytical signal is the spectral position of the photonic stop band. The signal linearly grows with the increase in the concentration of ethylene glycol and nonlinearly but monotonically increases with the growth in the concentration of ethanol. The fabricated sensors are characterized by a sensitivity to the concentration of ethylene glycol of about 0.413 nm/wt %.
