Method for solid-state in-situ synthesis of quantum dots in polymer matrix

The invention discloses a method for solid-state in-situ synthesis of quantum dots in a polymer matrix, which comprises the following steps: taking the polymer matrix as a solid-state solvent for synthesizing the quantum dots, and regulating and controlling the size of the quantum dots according to different thermal motion states of polymer molecular chains in different heating times of a polymer; the quantum dot-polymer composite material with different light-emitting wavelengths is prepared under the condition of not adding any ligand and surfactant. Through a transmission electron microscope photo, the quantum dots in the polymer are uniform in size and have good dispersity. The operation method is simple, a solvent post-treatment process does not exist, and the method is suitable for industrial large-scale production. The prepared quantum dot-polymer compound not only has higher luminous intensity and narrower half-peak width, but also keeps the long-time stability of the fluorescence of the quantum dot-p
