A photon-alignment optical film includes a film substrate on which at least one layer of core/shell nanoparticles is coated. The core/shell nanoparticle layer includes a plastic substance, which is photo curable or heat curable, and a plurality of core/shell nanoparticles, which is uniformly distributed in the plastic substance. Light energy is used as a driving force to induce electrical potential of the same polarity on the surfaces of the core/shell nanoparticles to make the core/shell nanoparticles rearranged in the form of a matrix due to repulsion induced between like electrical polarity. Spacing between the particles, which is relatively constant, allows light to pass therethrough. The plastic substance is cured by light or heat to have the core/shell nanoparticles set in position to thereby form the optical film. Such an optical film features both diffusion and brightness enhancement.
