| titleOfInvention | Light-emitting layer material, light-emitting device and light-emitting device |
| abstract | The present invention relates to a light-emitting layer material, a light-emitting device and a light-emitting device, wherein the light-emitting layer material includes at least one quantum dot material, at least one exciplex and at least one wide bandgap transport material; the exciplex The emission spectrum of the quantum dot material at least partially overlaps with the absorption spectrum of the quantum dot material; the decay lifetime of the excited state of the exciplex is greater than the decay lifetime of the excited state of the quantum dot material; the triplet of the wide bandgap transport material The energy level of the exciplex is higher than the triplet energy level of the exciplex. The above-mentioned light-emitting device applies the exciplex capable of forming delayed fluorescence together with the wide bandgap transport material to the light-emitting layer, which can effectively improve the light-emitting efficiency and stability of the device. |
