Overview

Randomized trial demonstrates enhanced luminescence in quantum dots for information encryption, indicating a significant advance in optical security materials.

Key Points

  • This research aims to synthesize high-entropy quantum dots (QDs) for improved luminescent performance and explore their potential in information encryption.
  • Synthesis of CuZnCrGaSe/ZnSe/ZnS core/shell/shell high-entropy QDs using a one-pot nucleation strategy.
  • Optimization of reaction parameters and composition ratios with a focus on defect passivation.
  • Integration of QDs into photonic crystals to create dual-mode nanocomposite films.
  • Achieved a photoluminescence quantum yield of 100%, the highest reported for alloy QDs.
  • Demonstrated dual reversible optical states: structural color and fluorescent color in the nanocomposite films.
  • Validated a visual encoding/decoding system for secure binary code conversion.
