Photonic crystal is a crystal form that reflects wavelength similar to the grid spacing of particles. Using these photonic crystal properties and spherical PS particles, a photonic crystal hydrogel sensor in the form of an inverse opal structure that is sensitive to alcohol vapor was fabricated. By using Ionic liquid in this sensor, low volatility and good thermal stability were achieved, and color tunability for absorption of alcohol vapor was enabled. The reaction of the analyzer was rigorously investigated under the temperature of the sensor and various concentrations or temperature conditions of alcohol vapor, and it was confirmed that non-alcoholic components contained in exhale were not detected. |
