The invention provides a preparation method and application of a nitrogen-carbon-based light conversion agent, as well as a light conversion plastic film and a preparation method thereof. Raw materials of the nitrogen-carbon-based blue-light conversion plastic film include a stable inorganic nitrogen-carbon-based light conversion agent with good compatibility with film matrix materials, matrix materials such as polyethylene, and auxiliary agents such as paraffin. The nitrogen-carbon-based light conversion agent has a composition of C₃NₓHᵧ, where 4 < x ≤ 4.01 and 0.00 < y ≤ 0.03. The light conversion plastic film of the invention can absorb ultraviolet rays in sunlight that cause plant diseases and convert the ultraviolet rays into blue light beneficial to plant growth. It features controllable concentration of the light conversion agent, uniform dispersion, convenient processing, and excellent thermal and light stability. The popularization and application of the film can prolong the service life of greenhouse films, raise the temperature in greenhouses, reduce crop diseases, and increase crop yields.
