The present invention relates to a rare earth/chlorophyll composite probe, a preparation method and application thereof. The general formula is: ReOF:Ln@chl, where Re and Ln are lanthanides, and chl is chlorophyll. The nanometer material in the rare earth/chlorophyll composite probe of the present invention has good fluorescence properties, is a good up-conversion fluorescent material, and has good luminescence effect, so it can carry out targeted labeling and localization of tumor tissue and cancer tissue, It is used to guide surgical resection of tumor tissue and cancer tissue, and by compounding chlorophyll on the surface of nanomaterials, the compound probe has better photodynamic effect, and can perform photodynamic therapy on tumors. |
