We harness the photophysics of few-atom silver nanoclusters to create the first fluorophores capable of Optically Activated Delayed Fluorescence (OADF). In analogy with thermally activated delayed fluorescence, often resulting from oxygen- or collisi

Excitation of few-atom Ag cluster fluorescence produces significant steady-state dark state populations that can be dynamically optically depopulated with long wavelength co-illumination. Modulating this secondary illumination dynamically repopulates

Fluorescence modulation offers the opportunity to detect low-concentration fluorophore signals within high background. Applicable from the single-molecule to bulk levels, we demonstrate long-wavelength optical depopulation of dark states that otherwi

Fluorescence intermittency severely limits brightness in both single molecule and bulk fluorescence. Herein, we demonstrate that optical depopulation of organic fluorophore triplet states opens a path to significantly increased sensitivity by simulta

The water-soluble, near-IR-emitting DNA-encapsulated silver nanocluster presented herein exhibits extremely bright and photostable emission on the single-molecule and bulk levels. The photophysics have been elucidated by intensity-dependent correlati

Cyanine dyes are well-known for their bright fluorescence and utility in biological imaging. However, cyanines also readily photoisomerize to produce nonemissive dark states. Co-illumination with a secondary, red-shifted light source on-resonance wit
