Optical Sensing and Imaging of Trace Oxygen with Record Response

Ultratrace quantities of oxygen can be determined at single spots as well as spatially resolved, and over a temperature range of more than 100 K, by exploiting the extremely efficient quenching of the delayed fluorescence of the fullerene C70 incorporated into matrices of organosilica or ethyl cellu...

Description
Summary:Ultratrace quantities of oxygen can be determined at single spots as well as spatially resolved, and over a temperature range of more than 100 K, by exploiting the extremely efficient quenching of the delayed fluorescence of the fullerene C70 incorporated into matrices of organosilica or ethyl cellulose.
