Embodiment 1
[0082] A light conversion film, comprising a light conversion material and a polymer film as a carrier, wherein the light conversion material is a composite of quantum dots and inorganic phosphors, and the polymer film is made of 184 silicone resin prepared.
[0083] The preparation method of this photoconverting film is as follows: 3ml CdSe / CdS red quantum dot solution (dissolved in chloroform, 10mg / mL) and 1g red inorganic fluorescent powder are mixed uniformly, and the gained mixed solution is mixed with 10g 184 silicone resin mixed to form a light-emitting composite, and then coated on the PET substrate, thermal curing (80 ° C, 5 minutes) to obtain.
Embodiment 2
[0085] A light conversion film comprises a light conversion material, a polymer film as a carrier, and two upper and lower protective isolation films. Wherein, the light conversion material is a composite quantum dot, and the polymer is a UV-curable glue with a refractive index of 1.48.
[0086] The preparation method of the light conversion film is as follows: 0.89ml GA_InP / ZnS green quantum dot solution (dissolved in chloroform, 10mg / mL) and 0.1189ml CdSe / CdS red quantum dot solution (dissolved in chloroform, 10mg / mL) were mixed uniformly; Mix the obtained quantum dot solution with 2g of UV-curable glue to form a light-emitting compound, and then coat it on a PET protective isolation film, form it by pressing the film, and obtain it by UV-curing; and then encapsulate the surroundings of the light conversion film.
Embodiment 3
[0088] A light conversion film comprises a light conversion material, a polymer nanofiber mat as a carrier, and two upper and lower protective isolation films. Among them, the light conversion material is composite quantum dots, the polymer nanofiber mat is polyvinylidene fluoride, and the refractive index is 1.42.
[0089] The preparation method of the light conversion film is as follows: mix 0.89ml GA_InP / ZnS green quantum dot solution (dissolved in chloroform, 10mg / mL) and 0.1189g CdSe / CdS red quantum dot solution (dissolved in chloroform, 10mg / mL); Coat, spray, or dip-coat the obtained quantum dot solution on a 20×40mm polyvinylidene fluoride nanofiber mat, and then dry it at low temperature (40°C, 15min); seal the nanofiber light-emitting layer on the PP protection layer with a thermosetting sealant. between the isolation membranes.
