The invention discloses a zinc oxide-zinc sulfide nano film. A manufacturing method of the zinc oxide-zinc sulfide nano film comprises the following steps that step one, zinc acetate is added into ethyl acetate and uniformly stirred, a pH agent is added to adjust the pH value to be 3-4, and liquid zinc is obtained; step two, oxalic acid is dropwise added into the liquid zinc and heated and stirred for 2-4 h, and distilled water is added for a slight boiling distillation reaction for 3-5 h; step three, a dispersant, conductive resin and graphene are added in to reaction liquid and heated and stirred till being completely dissolved; step four, a substrate is soaked into the reaction liquid in the step three, subjected to hydrothermal reaction for 2-3 h, taken out and dried; step five, the soaked substrate is put into a reactor, subjected to a low vacuum heating reaction for 3-5 h and naturally cooled to the room temperature; and step six, the substrate is soaked into absolute ethyl alcohol, and a hydrogen sulfide solution is dropwise added for reaction for 2-4 h to obtain the zinc oxide-zinc sulfide nano film. The zinc oxide-zinc sulfide nano film is easy to operate, high in yield and low in cost, and a novel method is provided for preparation of sulfide-oxide nano materials.
