The application provides a photoluminescent resin composition, a photoluminescent film, a transparent display film and a photoluminescent device. The composition comprises: resin, the resin is acrylic resin with benzene ring or polyurethane resin with benzene ring; organic photoluminescent material, the dosage is 0.1-5% of the resin weight; %～5%; and solvent, the dosage is 50～200 times of resin weight. Under the action of the dispersant, the luminescent material can have better dispersion in the resin, which is beneficial to the optical performance of the subsequent film formation; at the same time, through the control of the amount of each component, the molecular weight of the polymer formed by subsequent curing of the composition can be adjusted , so that its film-forming performance is better, so when it is applied in a photoluminescent device, the optical properties such as light transmittance and haze of the device are guaranteed. In addition, the use of organic photoluminescent materials greatly reduces the cost compared to the solution using quantum dots in the prior art. |
