Phosphorescence and delayed fluorescence properties of fluorone dyes in bio-related films

► Phosphorescence quantum yields of fluorone dyes in bio-related films are measured at room temperature. ► Delayed fluorescence quantum yields of fluorone dyes in bio-related films are measured at room temperature. ► Phosphorescence lifetimes of fluorone dyes in bio-related films are measured at room temperature. ► Delayed fluorescence lifetimes of fluorone dyes in bio-related films are measured at room temperature. ► General theory of short-pulse excited phosphorescence and delayed fluorescence is presented and relevant parameters are extracted.
