Disclosed in the present application are quantum dots and a preparation method therefor. The quantum dots comprise a group III-V quantum dot core and a surface ligand bound to a surface of the group III-V quantum dot core. The general formula of the chemical structure of the surface ligand is as shown in formula I: R1 and R2 are respectively at least one independently selected from among a halogen atom, a hydrogen atom, a hydroxyl group, a thiol group, an ether group, a thioether group, an aldehyde group, a carbonyl group, a carboxyl group, a nitro group, an amino group, a cyano group, an isocyano group, an epoxy group, an alkoxy group, an alkylcarbonyloxy group, an alkyloxycarbonyl group, an alkylcarbonyl group, a heteroaryl group, and a hydrocarbyl group. The surface ligand being bound to the surface of the group III-V quantum dot core is extremely helpful in the uniform growth of a housing layer such that the size distribution of the quantum dots becomes more uniform, ultimately being beneficial in improvi
