Abstract

We studied a facile and practical 1D photonic crystal sensor (PCS) for realtime colorimetric detection of BTX by the naked eyes with high selectivity. The 1D PC polymer films were prepared by a simple coating fabrication, which was immersed into BTX solutions, the colors change display obviously red (in benzene), yellow (in toluene) and green (in xylene) like traffic light as well as the color change from green to red as increase of benzene vapor concentration by the naked eyes. The response was very fast and it could be used reversible. Furthermore, 1D PCSs could be successfully used for discrimination between fake / adulterated gasoline and gasolines by colorimetric differentiation. It can be potentially used for monitoring of environment and chemical detection.
