Organic afterglow luminescence imaging detects photons that are being slowly released from chemical defects after the light source is turned off, enabling autofluorescence-free in vivo imaging with a high signal-to-background ratio. This Review discusses the mechanisms underlying organic afterglow luminescence, outlining organic afterglow probe design and optimization and highlighting key biomedical applications.
