The invention discloses a gelatinizable bismuth-based perovskite quantum dot with a core-shell structure as well as a preparation method and application of the gelatinizable bismuth-based perovskite quantum dot. The preparation method of the bismuth-based perovskite quantum dot with the core-shell structure comprises the following steps: 1) preparing a bismuth-based perovskite quantum dot precursor solution; 2) preparing bismuth-based perovskite quantum dots; and 3) preparing the bismuth-based perovskite quantum dot with the core-shell structure. The bismuth-based perovskite quantum dot with the core-shell structure has the advantages of high fluorescence efficiency, good stability, good dispersibility, safety, no toxicity and the like, and bismuth-based perovskite quantum dots with different morphologies and sizes can be obtained and gelation can be realized by adjusting the preparation process; the material can be used as a fluorescent material for cell identification, preparation of fluorescent products an
