The invention provides a hybrid bimetallic halide luminescent material and a preparation method thereof, and belongs to the field of luminescent materials. The luminescent materials are solvent coordinated A-site metal hybrid bimetallic halides, the chemical composition is A (L) n [BClm], A is a rare earth element, an alkaline earth metal element and a transition metal element, L is an organic solvent ligand, and B is an ns2 main group metal. The excitation wavelength of the luminescent material ranges from 250 nm to 450 nm, and the emission wavelength of the luminescent material ranges from 380 nm to 900 nm. The preparation method disclosed by the invention is simple in process, low in raw material cost and easy for large-scale technical popularization, and the material has high thermal quenching temperature and relatively high luminous efficiency. The luminescent material can be used for manufacturing luminescent devices, and can be applied to the fields of fluorescent powder, safety anti-counterfeiting and
