1. A light-emitting device comprising
a first electrode, a second electrode, and a light-emitting film disposed between the first electrode and the second electrode, wherein the light-emitting film comprises a fluorine-containing onium salt and quantum dots,
wherein the quantum dots do not comprise cadmium, lead, or a combination thereof, or hafnium, zirconium, titanium, or a combination thereof,
wherein the onium salt comprises a carbonium moiety, an oxonium moiety, a selenonium moiety, or a combination thereof, with a substituted or unsubstituted C1 to C30 hydrocarbon group, fluorine, and at least one of boron or phosphorus, and
wherein the onium salt is bound to the quantum dots.
