Description
In this communication, recent advances on the design, development and experimental validation of fluorescent indicators for barium tagging in double beta decay reactions of Xe-136 to yield one Ba(2+)-136 cation plus two electrons will be presented. These developments include mono- and bicolor indicators. The components of the fluorescent sensors include a Barium catcher and a fluorophore, together with a spacer-linker unit to anchor covalently the sensor to a suitable material in order to generate a functionalized surface able to detect Ba2(+) with low background and high selectivity. The photophysics of these sensors in solid-gas (Xe-136) interfaces will be also discussed.
