Abstract: A light-emitting device including an organic layer disposed between a first electrode and a second electrode, the organic layer comprising a fluorescent compound, wherein upon excitation, excitons in a 3n-π* excited state of the fluorescent compound migrate to a 1π-π* excited state of the fluorescent compound by reverse intersystem crossing with a Rate (rISC), and then undergo radiative transition to a ground state to emit light via fluorescence. The fluorescent compound is defined by a ratio of Rate (rISC) to Rate (IC) is 0.5 or greater. An electronic apparatus including the light-emitting device, and the fluorescent compound.
