Photoluminescence: Applications

Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Area of Science:

  • Materials Science
  • Optics
  • Nanotechnology

Background:

  • Multimodal optical materials offer enhanced information security but face challenges in independent modulation of structural coloration (SC) and fluorescence (FL) patterns.
  • Precisely controlling the orthogonal relationship between SC and FL is crucial for secure encryption applications.

Purpose of the Study:

  • To develop a strategy for multimodal information encryption by combining programmable structural coloration and switchable circularly polarized luminescence (CPL).
  • To achieve independent modulation of SC and FL patterns without mutual interference for robust security features.

Main Methods:

  • Fabrication of programmable periodic patterns on polydiacetylene (PDA) gel films using photomasks with aligned gratings for tunable SC.
  • Integration of a chiral fluorescence layer with perovskite nanocrystals and Ag nanowires (NWs) bilayers to achieve stimuli-responsive FL and CPL.
  • Utilizing microstructure design of cross-linked PDA gel and acetonitrile treatment for selective concealment or exposure of information.

Main Results:

  • Programmable SC patterns producing images in tunable structural colors were successfully fabricated.
  • The chiral fluorescence layer exhibited stimuli-responsive FL and CPL with a high dissymmetry factor (glum up to 1.3).
  • Independent modulation of SC and FL (including CPL) patterns was demonstrated without interference.

Conclusions:

  • The developed strategy enables independent control over structural coloration and switchable circularly polarized luminescence for multimodal information encryption.
  • This approach offers a promising platform for advanced optical security applications by allowing selective information concealment and exposure.
