Abstract

The invention discloses a Cu3BiS3 ternary sulfur nano material and a preparation method thereof, belonging to the field of inorganic nano materials. The Cu3BiS3 ternary sulfur nano material is nano particles which are prepared by adopting a high-temperature pyrolysis method by taking oleic acid, oleylamine and octadecene as reaction solvents, Cu(NO3)2.3H2O and Bi(NO3)3.5H2O as raw materials and sodium diethyldithiocarbamate as a complexing agent and a sulfur source. The Cu3BiS3 nano particles have better absorbability in an ultraviolet/visible light area, and are proved to have a good photo-thermal effect; besides, the Cu3BiS3 ternary sulfur nano particles can be used for performing CT (computed tomography) imaging, so that the nano particles can be well applied in the field of biomedicine. Moreover, the preparation method of the Cu3BiS3 ternary sulfur nano material has many advantages of simple operation, low raw material cost, availability and the like, and is suitable for industrial production and application.

Description

technical field [0001] The present invention relates to a kind of Cu 3 BY 3 A ternary chalcogen nanometer material and a preparation method thereof belong to the field of inorganic nanometer materials. Background technique [0002] Nanoparticles have attracted extensive attention due to their potential applications in biomedicine, such as molecular labeling, immunity, theranostics, and targeted delivery and therapy. Compared with traditional pharmaceuticals or therapeutic agents, the advantage of nanoparticles is that they can be modified to become better contrast agents for various imaging modalities, such as CT imaging, MRI imaging, and fluorescence imaging, etc. Good signal-to-noise ratio. [0003] Previously, there have been reports in the literature on the development of near-infrared photothermal agents as heat carriers for local hyperthermia, such as Au nanoparticles, graphene oxide (GO) nanoparticles, carbon quantum dots, etc., which can strongly absorb near-infra...
