1. A method for in-situ modification of mercury quantum dots in a traditional thermal injection process, comprising:
step I: preparing a precursor solution: mixing a mercury halide and an oleylamine to obtain a mixed system, heating the mixed system to 100° C., and fully stirring to form a precursor solution;
step II: rapidly injecting trimethylsilyl tellurium into the precursor solution and reacting at a reaction temperature of 80-120° ° C. to obtain a mixed reaction system, wherein a molar ratio of tellurium, mercury, and oleylamine is 0.5:1:48;
step III: during reacting the trimethylsilyl tellurium and the precursor solution, injecting a polar solvent into the mixed reaction system, and performing an in-situ surface modification of quantum dots in a two-phase dynamic interface; and
step IV: cooling the mixed reaction system, and conducting separation and purification to obtain a medium wave infrared mercury quantum dot solution;
wherein the polar solvent in step III comprises one or more selected from the group consisting of methanol, acetonitrile, water, acetone, chloroform, and isopropanol.
