Abstract
Embodiments of the invention relate to a composite film and a fabrication method thereof, a photoelectric element and a photoelectric apparatus. The fabrication method of the composite film includes: preparing a polyfluorene-based compound solution, wherein the polyfluorene-based compound solution includes polyfluorene or polyfluorene derivatives; preparing a quantum dot solution; mixing the polyfluorene-based compound solution and the quantum dot solution together to prepare a mixed solution; removing a solvent in the mixed solution to prepare the composite film.
