Implication

Randomized trial demonstrates multilevel data encryption in photonic capsules, indicating high security and storage density.

Key Points

  • This work aims to develop solid films that exhibit phototunable full-color circularly polarized luminescence for information encryption.
  • Constructed Förster resonance energy transfer platforms with chiral donors and achiral molecular switches in liquid crystal photonic capsules.
  • Fabricated device-friendly solid films with color tunability under UV irradiation.
  • Analyzed the time-dependence of CPL from initial blue emission to trichromatic signals.
  • Demonstrated photoswitchable CPL exhibiting RGB signals due to energy and chirality transfer synergies.
  • Observed strong time-dependent CPL changes based on varying Förster resonance energy transfer efficiencies.
  • Proven concept of multilevel data encryption using photonic capsule films.
