Summary:The present application discloses a composite material, a light-emitting diode, and a preparation method. The composite material comprises a first electron transport material and an indole-ring-containing compound doped into the first electron transport material. The composite material is used for preparing an electron transport layer. Therefore, the electron concentration of the electron transport layer can be increased, the loss of the electrons themselves is decreased, the dissipation of energy during electron injection is reduced, and the transmission efficiency of current carriers is improved; accordingly, the performance of a light-emitting diode is improved. La présente demande concerne un matériau composite, une diode électroluminescente et un procédé de préparation. Le matériau composite comprend un premier matériau de transport d'électrons et un composé contenant un cycle indole dopé dans le premier matériau de transport d'électrons. Le matériau composite est utilisé pour préparer une couche de tran
