Calcium-based efficient cathode-ray scintillating metal-organic frameworks constructed from π-conjugated luminescent motifs

Efficient cathode-ray scintillating metal-organic frameworks are constructed by π-conjugated luminescent motif and light Ca(II) ions. The luminescence self-quenching pathway has been effectively hindered through coordination. The in situ vacuum ultraviolet fluorescent spectra have witnessed the excitons recombination in the scintillation process for the first time.
