Abstract

An ethanol-assisted method is utilized to generate a robust gelated crystalline colloidal array (GCCA) photonic crystal sensor. The functionalized sensor efficiently diffracts the visible light and responds to various stimuli involving solvent, pH, cation, and compressive strain; the related color change can be easily distinguished by the naked eye.

摘要

采用乙醇辅助法制备了一种稳定的凝胶结晶胶体阵列（GCCA）光子晶体传感器。该功能化传感器能有效衍射可见光，并对溶剂、pH 值、阳离子和压缩应变等各种刺激做出响应；相关的颜色变化可以通过肉眼轻松识别。
