SPIE newsroom: ‘Simultaneous fluorescence and phosphorescence from organic molecules’

When all non-radiative channels of deactivation are effectively shut off, organic molecules turn into dual state emitters, giving rise to biluminescence. Here, only the effective mixing via intersystem crossing (ISC) and reverse ISC determine, which overall emission spectrum the molecules have. In an highlight article for the SPIE newsroom, Caterin Salas Redondo and I summarize what it takes to qualify as an efficient biluminophore.
