Fig. 5: The crossing point between polariton emission and phosphorescence.

a–c Angle dependent absorption (1-reflectance) (a), angle dependent prompt emission at room temperature (b), and angle dependent delayed emission at 77 K (c) of a cavity having similar parameters as Cavity 3. Fluorescence (dotted lines), phosphorescence (black solid lines), and fitted P– energy (green solid lines) are indicated. It should be noted that the excitation angle could not be held constant when performing angular dependent delayed emission experiments at 77 K. The emission dispersion plot in c is therefore normalized, with the consequence that information on the relative intensity of emission as a function of angle is lost.
