The present invention relates to an organic mixture and an application thereof in organic electronic devices. The organic mixture comprises a spirofluorene organic compound containing a fused heterocyclic ring and an aromatic fused heterocyclic organic compound containing an electron-donating group. A combination of the two materials may be used as a host material of a phosphorescent organic light-emitting diode (OLED), which may use the energy of excitons and balance the charge transport to the greatest extent and which may effectively reduce the concentration of excitons and the operating voltage of a corresponding device, thereby effectively improving the efficiency and service life of the related electronic device in order to provide an effective solution for improving the overall performance of an organic electronic device.
