Abstract
Disclosed are a light-emitting composite film, its manufacture method, and a white light organic electroluminescent device. Said light-emitting composite film comprises a first light-emitting layer and a second light-emitting layer. The first light-emitting layer comprises polyfluorene or polyfluorene derivatives, and the second light-emitting layer comprises quantum dots. A variety of color gamut and an improved brightness of devices can be achieved by the light-emitting composite film.
