UV-Activated Luminescence/Colourimetric O2 Indicator by Andrew Mills, Cheryl Tommons, Raymond T. Bailey, M. Catriona Tedford, Peter J. Crilly

“…An oxygen indicator is described, comprising nanoparticles of titania dispersed in hydroxyethyl cellulose (HEC) polymer film containing a sacrificial electron donor, glycerol, and the redox indicator, indigo-tetrasulfonate (ITS). The indicator is blue- coloured in the absence of UV light, however upon exposure to UV light it not only loses its colour but also luminesces, unless and until it is exposed to oxygen, whereupon its original colour is restored. …”
