Abstract
A quantum dot ink, a quantum dot film, a preparation method thereof and a display substrate are provided in the present disclosure, which relates to a technical field of displaying. The quantum dot ink includes: a first ink including at least a quantum dot body and a ligand coordinated on a surface of the quantum dot body, the ligand including an R1 group; and a second ink including at least a reactive compound, the reactive compound being configured for being capable of interacting with the R1 group and cause the quantum dot body to deposit to form a film. The quantum dot film prepared by the quantum dot ink has good film-forming uniformity, thus improving display effect of the display product prepared by the quantum dot film.
