Description

Technical field: [0001] The invention relates to the field of inorganic chemical industry, in particular to a synthesis method of a one-dimensional water-soluble CdHgTe nano-composite material with adjustable emission wavelength; the invention also relates to the application of the water-soluble CdHgTe nano-rod. Background technique: [0002] One-dimensional semiconducting nanomaterials (nanowires, nanorods, and nanotubes) have become a hotspot in nanotechnology research because of their high application potential in the technical field. So far, the synthesis of various one-dimensional nano-semiconductor materials is mainly limited to the organic phase or utilizes solvothermal methods. Aqueous phase synthesis has the advantages of simple method, low consumption, controllable surface properties, and biocompatibility, and has become a hot spot in the synthesis of semiconductor nanomaterials. However, semiconductor nanomaterials synthesized in aqueous phase usually have zero-di...
