T.Ba+2 ion trapping using organic submonolayer for ultra-low background neutrinoless double beta detectorART-2022-132741If neutrinos are their own antiparticles the otherwise-forbidden nuclear reaction known as neutrinoless double beta decay can occur. The very long lifetime expected for these exceptional events makes its detection a daunting task. In order to conduct an almost background-free experiment, the NEXT collaboration is investigating novel synthetic molecular sensors that may capture the Ba dication produced in the decay of certain Xe isotopes in a high-pressure gas experiment. The use of such molecular detectors immobilized on surfaces must be explored in the ultra-dry environment of a xenon gas chamber. Here, using a combination of highly sensitive surface science techniques in ultra-high vacuum, we demonstrate the possibility of employing the so-called Fluorescent Bicolor Indicator as the molecular component of the sensor. We unravel the ion capture process for these molecular indicators immobilized on a surface and explain the origin of the emission fluorescence shift associated to the ion trapping.2022http://zaguan.unizar.es/record/12523510.1038/s41467-022-35153-0http://zaguan.unizar.es/record/125235oai:zaguan.unizar.es:125235info:eu-repo/grantAgreement/ES/AEI/PID2019-107338RB-C63info:eu-repo/grantAgreement/EC/H2020/957202/EU/HINDERING DENDRITE GROWTH IN LITHIUM METAL BATTERIES/HIDDENThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 957202-HIDDENinfo:eu-repo/grantAgreement/ES/MICINN PID2019-104772GB-I00info:eu-repo/grantAgreement/ES/MICINN PID2019-111281GB-I00info:eu-repo/grantAgreement/ES/MICINN/PID2020-114252GB-I00info:eu-repo/grantAgreement/ES/MICINN/RTI2018-095979info:eu-repo/grantAgreement/ES/MINECO/CEX2018-000867-Sinfo:eu-repo/grantAgreement/ES/MINECO/RYC-2015-18820Nature communications 13, 1 (2022), 7741 [10 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
