Provided are an organic mixture and a composition containing same. The organic mixture comprises a first host material H1, a second host material H2 for forming an exciplex with the first main material H1, and an organic fluorescent light-emitting material E1, wherein the H1 and the H2 have a heterogeneous structure of II type, and the light-emitting wavelength of E1 is greater than or equal to that of the exciplex formed by H1 and H2. The present invention can be used for manufacturing a light-emitting device having the advantages of low costs, high efficiency, long service life and low roll-off. |
