Metal peroxide-based diagnosis and treatment integrated hybrid nano material as well as preparation method and application thereof

The invention discloses a metal peroxide-based diagnosis and treatment integrated hybrid nano material which is characterized in that the metal peroxide-based diagnosis and treatment integrated hybrid nano material is a hybrid nano material based on metal peroxide and a rare earth doped nanocrystalline scintillator, and the rare earth doped nanocrystalline scintillator and the metal peroxide are combined through the covalent bond effect. The material has fluorescence luminescence performance under X-ray excitation, and also has hydrogen peroxide self-supply performance. The invention also provides a preparation method of the material, which comprises the following steps of: modifying a metal peroxide by using cysteine to form a first dispersion liquid; forming a second dispersion liquid from a rare earth doped nanocrystalline scintillator; and adding the first dispersion liquid into the second dispersion liquid under a condition, carrying out ultrasonic treatment, stirring and reacting for 10-16 hours, and ta
