Overview

Demonstrates eco-friendly phosphorescent materials with humidity responsivity, suggesting innovative applications.

Key Points

  • The research aims to develop sustainable luminescent materials that exhibit room-temperature phosphorescence and humidity responsiveness.
  • Utilized carboxymethyl cellulose (CMC) as a matrix for material development.
  • Created a covalent cross-linked network through reaction with epichlorohydrin.
  • Incorporated 4,4′,4"-nitrilotribenzoic acid (NTA) into the network for enhanced properties.
  • Characterized the phosphorescent properties, stability in solvents, and humidity response of the resultant materials.
  • Achieved a maximum quantum yield of 44.44% for phosphorescence.
  • Demonstrated a maximum phosphorescence lifetime of 231.20 ms.
  • Maintained stable phosphorescence performance after immersion in organic solvents.
  • Enabled reversible writing and encryption with water as an 'ink'.
  • Facilitated drawing into fibers with distinct phosphorescent properties.
