The invention discloses a photoluminescent film and a preparation method and application thereof, wherein the preparation method of the photoluminescent film comprises the following steps: at least more than one quantum dot, photoinitiator, light scattering particles and resin are mixed and cured under the condition of keeping out of the sun to prepare the photoluminescence film. The invention prepares the photoluminescence film by introducing the free radical initiator into the quantum dot film. The free radical initiator is utilized to destroy the mixed quantum dots through the free radicals formed by light irradiation decomposition, so that the light color conversion is realized through the destruction of single quantum dots, the stability difference of the quantum dots is realized by controlling the synthesis process of the quantum dots, the color of the photoluminescence film is quantitatively controlled, and the indirect quantitative light energy is realized. The light source irradiates the photoluminescence film under different intensities and different distances to realize slow color change of the photoluminescence film, thereby realizing quantitative control of illumination energy. |
