Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Optoelectronics

Background:

  • Polysaccharide-based room-temperature phosphorescence (RTP) materials are attractive for anti-counterfeiting, data encryption, and optoelectronics due to their eco-friendly nature, flexibility, and transparency.
  • Existing materials often lack ultralong phosphorescence lifetimes and excitation wavelength-dependent afterglow properties.

Purpose of the Study:

  • To fabricate amorphous RTP materials with ultralong phosphorescence lifetimes and excitation wavelength-dependent emission.
  • To explore the potential of these materials in advanced applications like data encryption and anti-counterfeiting.

Main Methods:

  • Covalent bonding of sodium alginate (SA) with arylboronic acid in an aqueous phase to create amorphous RTP materials.
  • Characterization of RTP performance, including phosphorescence lifetime and excitation-dependent emission spectra.
  • Co-doping with fluorescent dyes to tune afterglow color via Förster resonance energy transfer (FRET).
  • Investigation of water/heat-responsive characteristics based on hydrogen bond sensitivity.

Main Results:

  • Fabrication of amorphous RTP materials with an ultralong phosphorescence lifetime of up to 2.52 seconds.
  • Observation of excitation-dependent emissions ranging from cyan to green.
  • Achieved color tunability from cyan to yellowish-green and near-white through co-doping and FRET.
  • Demonstrated water/heat-responsive RTP properties due to the sensitivity of hydrogen bonds in SA.

Conclusions:

  • The developed SA-based amorphous polymers exhibit promising ultralong RTP with tunable and stimuli-responsive characteristics.
  • These materials show successful application in data encryption and anti-counterfeiting, highlighting their potential for smart security features.
