aΦP was calculated by the phosphorescence component in the photoluminescence spectra. If phosphorescence was too weak to be distinguished from fluorescence in the photoluminescence spectra, ΦP was determined based on phosphorescence component associated with relevant lifetimes.
bNo phosphorescence was detected at room temperature.
cMeasured at 77 K.
