Organic plastic scintillator and preparing method thereof and light conversion device

The invention discloses an organic plastic scintillator and a preparing method thereof and a light conversion device, and belongs to the technical field of organic plastic scintillators. The preparingmethod includes the steps that liquor of a vinyltoluene solution with dispersed 2,5-diphenyloxazole is degassed in a sealed container, the obtained product is heated to 125 DEG C to 150 DEG C for thefirst time and reacted for 4 h to 8 h, and then is slowly cooled to the normal temperature, and a precursor is obtained; the precursor is heated to 120 DEG C to 140 DEG C for the second time and solidified to be cooled to the normal temperature. An implementation method of the organic plastic scintillator is simple and convenient, the formula is simple, raw materials are environmentally friendly, the organic plastic scintillator prepared with the method is free of bubbles, free of embrittlement, good in stability, free of toxic and side effects and high in light transmittance, resolution ratio and response speed.
