Abstract

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 %.

用于基于具有反蛋白石结构的薄膜的液体成分的光子晶体传感器

摘要

研究了使用由光刻胶制成的反蛋白石薄膜作为传感器来确定水中醇类浓度的可能性。分析信号是光子阻带的光谱位置。信号随着乙二醇浓度的增加线性增长，随着乙醇浓度的增长非线性但单调增加。制造的传感器的特征在于对乙二醇浓度的敏感性约为 0.413 nm/wt%。
